	[ftinspect] Fix DPI scaling.

	* src/ftinspect/glyphcomponents/glyphcontinuous.[ch]pp:
	    Scale back the QPainter against the device scale factor to disable scaling
	    temporarily for the QPainter.
	    This make the continuous view look identical for all DPI settings when in
	    the px-based font size mode. The default view in the pt-based mode will
	    depend on the system DPI settings.

	[ftinspect] Use iconv or Windows `WideCharToMultiByte` to convert charset.

	In Qt 6, `QTextCodec` was removed and for platforms where Qt is not built
	against iconv, the modern `QStringDecoder` has no support for non-Unicode
	codecs, either. This necessitates the use for iconv on Unix/Linux systems,
	and/or `WideCharToMultiByte` on Windows.

	* src/ftinspect/CMakeLists.txt: add optional depenedency for iconv
	* src/ftinspect/engine/stringrenderer.cpp: as mentioned above.

	destroyed, or the event connection between the singular tab and the glyph view
	scroll will trigger a crash when exiting.

	* src/ftinspect/panels/singular.[ch]pp: as is described above.

	* src/ftinspect/CMakeLists.txt:
	    Change minimal CMake version to 3.19 to enable Presets.
	    Change minimal C++ version to C++17 because Qt6 requires that.
	    Enable both Qt 5/6 and take advantage of new Qt6-specific CMake infras.
	* src/ftinspect/engine/fontinfo.cpp:
	    Fix the `QStringDecoder` usage.
	* src/ftinspect/engine/stringrenderer.cpp:
	    TODO: only minimal changes are done and the `convertCharEncoding` is not
	    functional for Qt 6.

	[graph] Fix graph/x11/rules.mk for X11_CFLAGS handling.

	* graph/x11/rules.mk: X11_CFLAGS is set by
	  `pkg-config --cflags x11`, which pkg-config puts `-I`
	  already.  Using `$I` is a convention of FreeType2 to
	  neutralize CFLAGS, but `$I$X11_CFLAGS` causes an
	  invalid CFLAGS like `-I-I`.  Using subst like
	  `$(subst -I,$I,...)` is safer.

	Fix issue #27.

	[ftinspect] Add PostScript constructed name display for MM/GX fonts.

	Fixes #57 . Added a text box showing current constructed PostScript name
	with MM/GX coords included according to TN #5902.

	* src/ftinspect/panels/settingpanelmmgx.cpp,
	  src/ftinspect/panels/settingpanelmmgx.hpp:
	  Add the PostScript name text box.
	  Track the dirty state of the axes, so when all axes are in "default" state
	  the "basic" PS name will be displayed (e.g. "NotoSansCJKtc-DemiLight"),
	  while when any axis has its value modified, the constructed PS name will
	  be displayed (e.g. "NotoSansCJKTC_350wght").
	  Even when the value equals to the default one, as long as the value was
	  touched by user, the name will be the constructed one. To clear the dirty
	  state, the "Def" button for each axis, or the "Reset to Default" button
	  should be used.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add two fields tracking PS name (one with "basic" name, and one possibly
	  constructed from MM/GX coords).

	* src/ftinspect/engine/fontinfo.cpp: Change to use the PS name from engine.

2023-10-05  Charlie Jiang  <w@chariri.moe>

	  Use the highest bit of `FTC_FaceID` to indicate that the face/size is for
	  rendering (safe for some modification to the face, e.g. MM/GX coords).

	ftlint.1: Instruct man(1) to run the groff `tbl` preprocessor

	The latest version of groff (1.23.0) emits a warning when it detects the
	use of table macros (.TS, .TE) with no .TW (table width) macro defined:

	  tbl preprocessor failed, or it or soelim was not run; table(s) likely
	  not rendered (TE macro called with TW register undefined).

	The warning occurs because the `tbl` preprocessor was not invoked by
	the `man` command. To fix the issue, we need to instruct man(1) to
	run the `tbl` preprocessor before rendering the source as text.

	This issue was detected by Debian's Lintian tool.

	Now the named instance selector no longer doubles the default named instance.
	`FT_Get_Default_Named_Instance` is used to get the default NI index.
	The default one is labeled as " (default)".

	* src/ftinspect/widgets/tripletselector.cpp: Properly handle the new 1-based
	  named instance indices. Label the default NI correctly.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:

	[ftinspect] Fix the glyph index selector layout when the window resizes.

	Fixes #26. When the window resizes, the invisible tabs don't get notified.
	Therefore, when the active tab changes, we need to trigger a manual
	relayouting of invisible tabs.

	* src/ftinspect/widgets/glyphindexselector.hpp,
	  src/ftinspect/widgets/glyphindexselector.cpp:
	  Extract public method `relayoutNavigation` from `resizeEvent`.

	* src/ftinspect/panels/abstracttab.hpp: Add `relayout` virtual method.

	* src/ftinspect/maingui.cpp: Call `AbstractTab::relayout` on the new tab
	  when the active tab changes.

	* src/ftinspect/panels/singular.cpp, src/ftinspect/panels/singular.hpp,

	src/rsvg-port.c: Correct usage of `FT_Bool` vs `gboolean` comparison.

	`TRUE` in this context is from glib headers (`glib-2.0/glib/gmacros.h`),
	imported indirectly from rsvg headers.  It should not be used for comparison
	with `FT_Bool` types.  Other usages of `TRUE/FALSE` in this file is okay.

2023-07-08  Hin-Tak Leung  <htl10@users.sourceforge.net>

	rsvg-port.c: Simplify usage of `rsvg_handle_render_*`.

	* src/rsvg-port.c (rsvg_port_preset_slot): Remove usage of
	`rsvg_handle_render_document` (and `rsvg_handle_render_cairo`).  They are
	functionally the same as `rsvg_handle_render_layer` (and
	`rsvg_handle_render_cairo_sub`) with argument id set to NULL.

	* src/rsvg-port.c (rsvg_port_preset_slot): Fix C++ compilation warning.

2023-06-03  Hin-Tak Leung  <htl10@users.sourceforge.net>

	Fix out-of-memory conditions with newer 'librsvg'.

	Excerpts from `rsvg_handle_get_intrinsic_dimensions` section in
	`librsvg/rsvg.h`:

	```
	Before librsvg 2.54.0, the `out_has_width` and `out_has_height` arguments
	would be set to true or false depending on whether the SVG document actually
	had `width` and `height` attributes, respectively.

	However, since librsvg 2.54.0, `width` and `height` are now [geometry
	properties](https://www.w3.org/TR/SVG2/geometry.html) per the SVG2
	specification; they are not plain attributes.  SVG2 made it so that the
	initial value of those properties is `auto`, which is equivalent to
	specifying a value of `100%`.  In this sense, even SVG documents which lack
	`width` or `height` attributes semantically have to make them default to
	`100%`.  This is why since librsvg 2.54.0, `out_has_width` and
	`out_has_heigth` are always returned as `TRUE`, since with SVG2 all
	documents *have* a default width and height of `100%`.
	```

	* src/rsvg-port.c (rsvg_port_preset_slot): Adjust for change of behavior of
	`rsvg_handle_get_intrinsic_dimensions` in librsvg 2.53+.  We avoid
	`LIBRSVG_CHECK_VERSION` as it is possible to build against one version but
	run against another version.

2023-06-03  Hin-Tak Leung  <htl10@users.sourceforge.net>

	Fix 'librsvg' deprecation warnings.

	* src/rsvg-port.c (rsvg_port_preset_slot): Use `rsvg_handle_render_document`
	instead of `rsvg_handle_render_cairo`, and `rsvg_handle_render_layer`
	instead of `rsvg_handle_render_cairo_sub`, as suggested by the warning,
	conditionally on newer librsvg 2.52+.

	Correct type of icon_span

	The `icon_span` is used as a `FT_SpanFunc`. To avoid undefined behavior
	and a CFI sanitizer report, this function needs to called through a
	pointer of the same type. Fix this by making `icon_span` take the right
	parameter types and cast the argument in the function body.

	* src/ftcommon.c (icon_span): take correct parameters and cast in
	function body. (FTDemo_Icon): remove cast

2023-05-12  Ben Wagner  <bungeman@chromium.org>

	[graph] Correct function pointer types

	Building the demos with the CFI sanitizer detects a number of uses of
	undefined behavior in the Minimalist Graphics Subsystem where an
	indirect function call is made through a pointer of a different type.
	All of these cases worked in practice since the differing argument
	types were the same size and would have the same pointer value at
	runtime.

	Change the functions to take the correct types and downcast inside the
	function.

	* graph/beos/grbeos.cpp: remove casts

	* graph/mac/grmac.c: correct return type of `listen_event`, remove casts

	* graph/os2/gros2pm.c: correct function signatures, downcast inside
	functions, remove function pointer casts

	* graph/win32/grwin32.c: ditto

	[ftlint] Examine the outline shape complexity.

	Measured as a ratio of the outline half-perimeter to the sum of its

	For example, an `I` and an `M` would have complexities of about
	1.0 and 2.0, respectively.

	these two macros as (different) case labels in switch statements.

	* src/ftbench.c (tt_interpreter_versions, header, usage, main): Don't use
	`TT_INTERPRETER_VERSION_38`.

2023-02-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[ftmulti] Enable fill rule flag testing.

	Variation fonts often relay on overlapping contours. To reveal them,
	we enable turning the even-odd fill rule on and off. This flag is
	always off in FreeType by default but supported by the anti-aliased
	renderer.

	* src/ftmulti.c (Process_Event): Reassign F3 to fill rule toggle,
	assign Tab to anti-aliasing toggle.
	(Render_Glyph): Tinker with the fill rule flags before rendering.

2023-02-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftmulti.c: Clean up and fix warnings.

2023-02-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftmulti.c (Process_Event): Miscellaneous tweaks.

	Set default step at 1/40 which covers most preferable coordinates.
	Adjust the step by doubling or halving it. Round all large-range
	coordinates, not just MM. Wrap the coordinates around.

2023-02-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftmulti.c (Render_All, Render_Text, main): Layout tweaks.

2023-02-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[ftmulti] Enable overlap flag testing.

	Variation fonts often relay on overlapping contours, which require
	oversampling to render properly. FreeType relies on FT_OUTLINE_OVERLAP
	to trigger the expensive mitigation algorithm. This commit enables
	tinkering with the overlap flags and, therefore, the oversampling.
	Normally, the flags should be set by the font designers sparingly.

	The bitmap strike toggle is no longer available, which has never
	been important for the variation font testing.

	* src/ftmulti.c (Process_Event): Reassign F4 to overlap toggle.
	(Render_Glyph): Tinker with the overlap flags before rendering.

2023-02-11  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftmulti.c (Init_Display): Use automatic color depth.

2023-02-11  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftmulti.c (main): Synchronize options with the others.

2023-02-09  Werner Lemberg  <wl@gnu.org>

2023-02-09  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/win32/grwin32.c (Message_Process): Drop some sizing messages.

	With the window procedure in a separate thread we only need to forward
	basic WM_SIZE, which is sent frequently enough.

2023-02-08  Werner Lemberg  <wl@gnu.org>

	Fix various minor compiler warnings.

2023-02-08  Werner Lemberg  <wl@gnu.org>

	[ftgrid] Synchronize with FreeType git.

	The changes are necessary due to the commit

	```
	Avoid reserved identifiers that are globally defined.
	```

2023-02-08  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[ftmulti] More key reassignments.

	This is a try to better harmonize with other demo programs, and to make the
	selection of axes more mnemonic.

	* src/ftmulti.c (MAX_MM_AXES): Set to 16.
	(Process_Event): Use keys 'aA' for axis 0, 'bB' for axis 1, ..., 'pP' for
	axis 16.
	Use F1 for help, too.
	Use 16, 256, and 4096 as the glyph index increments.
	Also adjust other keys to avoid collisions.
	(Help): Updated.
	(main): Show mnemonic letter next to axis.
	Updated.

2023-02-05  Werner Lemberg  <wl@gnu.org>

	[ftmulti] Display up to 15 axes.

	Due to the support of the 'avar' version 2 OpenType extension it is expected
	that the number of axes in many fonts will increase because adding 'virtual
	axes' is cheap now.

	* src/ftmulti.c (MAX_MM_AXES): Set to 15.
	(Help): Updated.
	(Process_Event): Handle keys '7890-=' for axes 6-8, '!@#$%^' for axes 9-11,

	* src/ftinspect/engine/fontinfo.hpp,
	  src/ftinspect/glyphcomponents/glyphcontinuous.cpp: Clearify comments.

	* src/ftinspect/glyphcomponents/glyphoutline.cpp,
	  src/ftinspect/glyphcomponents/glyphoutline.hpp:
	  Don't retain the `FT_Outline*` whose lifetime is bound to the glyph.
	  Prepare the path in the ctor so the outline isn't saved.
	  Add `GlyphUsingOutline` as the base class for all classes that have to
	  retain a `FT_Outline` object.

	* src/ftinspect/glyphcomponents/glyphpointnumbers.cpp,
	  src/ftinspect/glyphcomponents/glyphpointnumbers.hpp,
	  src/ftinspect/glyphcomponents/glyphpoints.cpp,
	  src/ftinspect/glyphcomponents/glyphpoints.hpp: Refactored.

	Note: Untested since no font with non-1.0 scale subglyphs is found.

	* src/ftinspect/engine/fontinfo.cpp, src/ftinspect/engine/fontinfo.hpp:
	  Fetch transformation and scaling info from the font.

	* src/ftinspect/models/fontinfomodels.cpp,
	  src/ftinspect/models/fontinfomodels.hpp:
	  Change the "Position" column to "Position and Transformation".
	  Display the transformation info.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Improve bitmap display in the glyph details pane.

	Now the ppem square is displayed as light gray, ink box as blue,
	xy-axis as thin black lines.
	Adding ppem square improves displaying of non-spacing glyphs.

	* src/ftinspect/panels/glyphdetails.cpp:
	  Pass the ppem box to the `GlyphBitmap` widget.

	* src/ftinspect/glyphcomponents/glyphbitmap.cpp,
	  src/ftinspect/glyphcomponents/glyphbitmap.hpp:
	  Add a `placeholderRect` to store the ppem square info. Layout the glyph

	  parse the font data.

	* src/ftinspect/models/fontinfomodels.cpp,
	  src/ftinspect/models/fontinfomodels.hpp:
	  New files. Add models for the tables and the tree view in the info tab to

	  Add getters.

	* src/ftinspect/engine/fontinfonamesmapping.cpp: New file for name mapping.

	* src/ftinspect/engine/fontfilemanager.cpp,
	  src/ftinspect/engine/fontfilemanager.hpp:
	  Add `currentReloadDueToPeriodicUpdate` so the composite glyph tree isn't
	  refreshed (which is a very expensive process) for the periodic updating of
	  symbolic font files.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp:
	  Add the font info tab info the main window and wire events.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	Left clicking will open the glyph details pane, and right clicking will
	switch to the singular tab.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Add SFNT `name` table retrieving.

	* src/ftinspect/engine/fontinfo.cpp, src/ftinspect/engine/fontinfo.hpp:
	  New files, add `SFNTName` to retrieve `name` table.
	  Conversions to `QString` from mainstream encodings are supported.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:

	[ftinspect] Support MM/GX.

	* src/ftinspect/panels/settingpanelmmgx.cpp,
	  src/ftinspect/panels/settingpanelmmgx.hpp:
	  Add GUI widgets for MM/GX settings.

	* src/ftinspect/engine/mmgx.cpp, src/ftinspect/engine/mmgx.hpp:
	  Add `MMGXAxisInfo` to retrieve axes info. However, the SFNT name table
	  isn't implemented, so the SFNT based axis names are unavailable.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add `applyMMGXDesignCoords`. Add getters `currentFontMMGXState` and
	  `currentFontMMGXAxes`. Info is retrieved when loading font.

	* src/ftinspect/panels/settingpanel.cpp,
	  src/ftinspect/panels/settingpanel.hpp: Uncomment functional code.
	  Remove `checkHintingMode` and `checkStemDarkening`. Applying of delayed
	  settings is taken care by the `MainGUI`. So emitting `fontReloadNeeded`
	  simply will do the work.

	* src/ftinspect/maingui.cpp: Don't reset the cache so aggressively.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

	* src/ftinspect/panels/settingpanel.cpp: Uncomment functional code.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Support color layers.

	* src/ftinspect/engine/rendering.cpp:
	  Add implementation of `tryDirectRenderColorLayers`.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Implement `loadPaletteInfos` and `loadPalette`.
	  Add `currentFontHasColorLayers` and a group of getters/setters supporting
	  color layer rendering.
	  Also reorder fields as the number of fields grows.

	* src/ftinspect/panels/settingpanel.cpp,
	  src/ftinspect/panels/settingpanel.hpp:
	  Implement `populatePalettes` and reorder functions.
	  Fix `checkPalette` about combo box enabling state and reset the cache when
	  the palette settings change.
	  Uncomment functional code.

	* src/ftinspect/engine/paletteinfo.cpp,
	  src/ftinspect/engine/paletteinfo.hpp: New files adding `PaletteInfo`.
	  Retrieving palette names using SFNT name tables is not supported yet.

	* src/ftinspect/panels/singular.cpp:
	  Call `Engine::loadPalette` when drawing.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Support tricky fonts.

	For tricky fonts, we disable auto-hinter and limit the TT interpreter
	version.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add `currentFontTricky` function and turn off hinting forcibly when the
	  user turns it off in the GUI for tricky fonts.

	* src/ftinspect/panels/settingpanel.cpp: As described.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Support embedded bitmap and bitmap-only fonts.

	Bitmap glyphs are already supported in the new rendering engine, so we make
	the option effective in the GUI. Also support bitmap-only fonts by coercing
	sizes to available ones and force embedded bitmaps.

	* src/ftinspect/widgets/fontsizeselector.cpp,
	  src/ftinspect/widgets/fontsizeselector.hpp:
	  Retrieve fixed sizes info from the engine and coerce to nearest available
	  sizes when using bitmap-only fonts.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add `embeddedBitmapEnabled` property and `currentFontHasEmbeddedBitmap`,
	  `currentFontBitmapOnly` and `currentFontFixedSizes` getters.

	* src/ftinspect/panels/settingpanel.cpp: Uncomment functional code.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Refactor `Engine` and fix the singular tab.

	This comment brings the new glyph loading and bitmap rendering code.
	The bitmap rendering part is in `RenderingEngine` which can be obtained
	from the `Engine`. The `Engine` now supports loading the glyph by loading
	with image cache and without image cache.
	The `loadOutline` function is removed.

	Accompanying this change, some new features are introduced as well. Most
	notable the improvements in rendering: back/foreground color and gamma,
	support bitmap glyphs (not enabled in the UI). Support for LCD and color
	layer font is absent yet.

	The singular tab is now enabled by uncommented functional code that was
	commented in the last commit.

	In `Engine`, a `ftFallbackFace_` is introduced for all non-rendering work,
	and the old `ftSize_` is only used for rendering. This helps dealing with
	non-scalable fonts since we can safely retrieve info with the fallback face.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Integrate the `RenderingEngine`.
	  Change `loadFont` to update the `ftFallbackFace_` as well.
	  Change all info-retrieving functions to use `ftFallbackFace_`.
	  Add `loadGlyph`, `loadGlyphIntoSlotWithoutCache` and
	  `loadGlyphWithoutUpdate`, and remove `loadOutline`.
	  Extract code about "get a face object from the cache and do sth."
	  into a new function `withFace`.
	  Add property `antiAliasingEnabled` and `renderMode` for the rendering
	  engine.
	  Some minor changes are included.

	* src/ftinspect/engine/rendering.cpp, src/ftinspect/engine/rendering.hpp:
	  New files, as described.

	* src/ftinspect/panels/settingpanel.cpp,
	  src/ftinspect/glyphcomponents/glyphbitmap.cpp,
	  src/ftinspect/panels/singular.cpp: Uncomment functional code.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Add the `SingularTab` and related widgets.

	This introduces the new singular tab. However, because the new tab heavily
	depend on the new engine structure, it's current not functional. No bitmap
	or outline will be displayed. This would be fixed after the `Engine` was
	refactored in the next commit.

	The new singular tab has the size and glyph index selector moved out as
	modular widgets to be reused.

	The new scroll and shortcut behaviours are introduced in this commit, which
	depend on scroll events introduced in the custom `QGraphicsViewx`.

	The infinity panning of grid is implemented mainly via
	`SingularTab::updateGrid` and `Grid::updateRect`.

	This commit is introducing new features since it would be unfavorable to
	"backport" old version of glyph components, and add those new features in
	future commits - this is way too complex.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add `currentFontNumberOfGlyphs` and `dpi` functions.

	* src/ftinspect/widgets/fontsizeselector.cpp,
	  src/ftinspect/widgets/fontsizeselector.hpp:
	  This is the new font size selector to replace the old size/DPI/zoom boxes.
	  This widget is capable of handling wheel and key events delegated from
	  other widgets.
	  The support for fixed sizes and bitmap-only font is not yet added.

	* src/ftinspect/widgets/glyphindexselector.cpp,
	  src/ftinspect/widgets/glyphindexselector.hpp:
	  This is the new glyph index selector to replace the old navi buttons.
	  This selector is aware of index min/max, consists of a group of navi
	  buttons, a text box (actually a spin box without buttons) to directly
	  input glyph index.

	* src/ftinspect/glyphcomponents/graphicsdefault.cpp,
	  src/ftinspect/glyphcomponents/graphicsdefault.hpp:
	  This struct contains all default graphical settings (mainly for singular
	  view, e.g. the grid line color).

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp:
	  Add the new tab into the main window.

	* src/ftinspect/glyphcomponents/glyphbitmap.cpp,
	  src/ftinspect/glyphcomponents/glyphbitmap.hpp:
	  This will now delegate rendering to the engine instead of doing rendering
	  itself. However, since the rendering part of the `Engine` is not
	  implemented, code initializing `image_` is left commented.
	  Also add another constructor for initializing directly from a `QImage`.

	* src/ftinspect/glyphcomponents/glyphoutline.cpp,
	  src/ftinspect/glyphcomponents/glyphoutline.hpp,
	  src/ftinspect/glyphcomponents/glyphpointnumbers.cpp,
	  src/ftinspect/glyphcomponents/glyphpointnumbers.hpp,
	  src/ftinspect/glyphcomponents/glyphpoints.cpp,
	  src/ftinspect/glyphcomponents/glyphpoints.hpp:
	  Constructors of those items now accept a `FT_Glyph` instead of
	  `FT_Outline`. The conversion is done inside the view, and the view won't
	  be displayed if the glyph isn't outline glyph.
	  This simplifies the code of `SingularTab`.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Rewrite `MainGUI`.

	Note: This commit compiles, but the main view is removed, so you will get a
	blank right panel. The singular view will be added back with major changes
	in the next commit.

	This commit mainly introduces below changes:

	1. The original `MainGUI` contains almost all GUI elements. Most of them are
	   taken out to modular components. The current `MainGUI` serves only as
	   a skeleton provides coordinate between components, greatly shortened.
	   It also provides some auxiliary code such as calling to file chooser.
	2. The left panel is moved to `SettingPanel` class. The current
	   `settingpanel.[ch]pp` are directly modified from the latest code, so they
	   contains some options not implemented in the `Engine`.
	   Structural code that is only added accompanying later change is removed,
	   such as the comparator mode. Such code will be added back with the
	   related feature. However, code for unimplemented options are simply
	   commented out.
	3. The main part is transformed into a tabbed view. The original code is
	   removed. Refactored, it will be added back in the next commit.
	4. The navigation buttons (Next/Prev Font/Face/NI) are changed into the new
	   triplet-selector, which is a major UI improvement.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: As described.

	* src/ftinspect/panels/abstracttab.hpp: Add `AbstractTab` which is an
	  interface for all tabs listening for font reloading and repainting.

	* src/ftinspect/panels/settingpanel.cpp,
	  src/ftinspect/panels/settingpanel.hpp:
	  As described, this is the left panel. This requires intensive reviewing
	  since many bugs had rooted here.

	* src/ftinspect/widgets/tripletselector.cpp,
	  src/ftinspect/widgets/tripletselector.hpp:
	  As described, this is the triplet (Font/Subface/NI) selector.
	  This component is also responsible for repopulating triplet information
	  and keep up with the font file change (i.e. the
	  `FontFileManager::currentFileChanged` event is captured here).

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  Add `fontValid` and `namedInstanceName` since `TripletSelector` requires
	  them. However, they'll subject to change later.

	* src/ftinspect/ftinspect.cpp: Remove call to `MainGUI::setDefaults`.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] WIP: Rewrite `MainGUI`.

	Note: This commit doesn't compile. This change is splitted into 2 commits
	to avoid a complicated diff.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: Old version removed.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Rename `rendering` dir to `glyphcomponents`.

	All classes in `rendering` directory will be responsible for draw
	glyphs, either as independent widgets or as `QGraphicsItem`. However, the
	actual drawing part will be placed into `RenderingEngine`. Therefore, we
	rename it to `glyphcomponents`.

	* src/ftinspect/rendering/**: Renamed.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build,
	  src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Re-organize custom widgets.

	* src/ftinspect/widgets/customwidgets.cpp,
	  src/ftinspect/widgets/customwidgets.cpp: New files.
	  Include `QGraphicsViewx`, `ZoomSpinBox` and `UnboundScrollArea` (for later
	  use).

	* src/ftinspect/widgets/qspinboxx.hpp, src/ftinspect/widgets/qspinboxx.hpp:
	  Changed into `ZoomSpinBox` in `customwidgets.cpp`.

	* src/ftinspect/widgets/qgraphicsviewx.cpp,
	  src/ftinspect/widgets/qgraphicsviewx.hpp:
	  Merged into `customwidgets.cpp`

	* src/ftinspect/widgets/qcomboboxx.hpp,
	  src/ftinspect/widgets/qcomboboxx.cpp: Removed. No longer needed.
	  We're using custom `QAbstractListModel`'s `flags` func to disable items.

	* src/ftinspect/widgets/qpushbuttonx.hpp,
	  src/ftinspect/widgets/qpushbuttonx.cpp: Removed. No longer needed.
	  We're using `setButtonNarrowest` in `uihelper.cpp`.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: Updated to use new
	  custom widgets.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Use custom `QAbstractListModel` instead of manually mapping.

	In `maingui.cpp`, mapping between `QComboBox` indices and actual FreeType
	values was done manually. The enabled statuses of individual ComboBox items
	were also maintained in `maingui.cpp`.

	In this commit, those code was moved to seperate custom classes
	implementating `QAbstractListModel`. All mapping was done there.
	Enable/Disable states was maintained in the classes as well.
	By doing this, the reason why some items were disabled was made more clear
	and explicit. Adding more items is easier.

	The `QComboBoxx` custom widget is no longer needed since disable flag can
	be provided by the custom model by overriding the `flags` function.

	`SimpleComboBoxModel` is a basic class for Key-Value-DisplayName mapping.
	Other models could extend this class if no complicated mapping (e.g.
	`HintingModeComboBoxModel`) is needed.

	* src/ftinspect/models/customcomboboxmodels.cpp,
	  src/ftinspect/models/customcomboboxmodels.cpp: New files.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  `Engine` now accepts "load target" value of certain anti-aliasing mode
	  instead of the anti-aliasing enum value. The mapping was moved into
	  `AntiAliasingComboBoxModel`.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: Move all mappings
	  and enabled/disabled statuses to separate models.
	  Remove mapping `QHash`es. Use `QComboBox` instead of `QComboBoxx`.

	* src/ftinspect/meson.build, src/ftinspect/CMakeLists.txt: Updated.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Rename all private member variables with an underscore suffix.

	(pure mechnical commit)

	* src/ftinspect/**: Renaming. Also some variables with abbreviations
	were renamed.

	This will enable nicer getter/setters, as discussed in #13.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Refactor `Engine`.

	This commit decouples `Engine` so it no longer depends on `MainGUI`.

	Because of that, a lot of getters and setters are added to `Engine`, and
	`MainGUI` call setters in its `applySettings` function, which makes applying
	of the settings lazy (only happen when the glyph repaints).

	In the later commits, options will be divided into two types: mostly lazy
	ones, and a few eager ones which need to be immediately applied, because
	they need the cache to be purged.

	Some code in `MainGUI` is moved into `Engine`, as well.

	Functions in the `Engine` are re-ordered. Constructor is greatly reduced to
	`queryEngine`.

	* src/ftinspect/engine/engine.cpp, src/ftinspect/engine/engine.hpp:
	  As described.

	* src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp:
	  As described.

	* src/ftinspect/ftinspect.cpp: Remove dependency of `Engine` against
	  `MainGUI`.

2022-09-25  Charlie Jiang  <w@chariri.moe>

	[ftinspect] Move out font file managing/watching out to a new class.

	Introduce the feature that rejects invalid files.

	* src/ftinspect/maingui.hpp, src/ftinspect/maingui.cpp: Move `fontList`,
	  `fontWatcher`, `timer` and other code related to font file managing to
	  new class `FontFileManager`.

	* src/ftinspect/engine.hpp, src/ftinspect/engine.cpp:
	  `Engine` class now holds `FontFileManager`.
	  Also, make `MainGUI` open and close fonts indirectly via `Engine`.

	* src/ftinspect/fontfilemanager.hpp, src/ftinspect/fontfilemanager.cpp:
	  New files.

	* src/ftinspect/CMakeLists.txt, src/ftinspect/meson.build: Updated.

	* graph/grobjs.* (grAlloc): Return void pointer.

2022-09-06  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Fortify channel cache.

	Using signed short offsets in the channel cache will risk to overflow
	if the current cache size is to increase.  Here we switch to unsigned
	index and express it in the cache units.

	* graph/gblender.h (GBlenderChanKeyRec): Update `index`.
	* graph/gblender.c (gblender_clear, gblender_lookup_channel,
	gblender_reset_channel_key): Updated accordingly.

	Fixes #18.

2022-08-29  Alexei Podtelezhnikov  <apodtele@gmail.com>

2022-08-29  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Rework #ifdef GBLENDER_STORE_BYTES.

	This also settles on tripling the number of channel keys, which is
	a safe bet in all circumstances.  Quadrupling might only work on
	64-bit architectures or with added key structure padding, without
	GBLENDER_STORE_BYTES defined.

	* graph/gblender.h (GBlenderCell): Change definition.
	* graph/gblblit.c (GDST_STOREB): Updated accordingly.
	* graph/gblender.c (gblender_clear, gblender_reset_key,
	  gblender_lookup, gblender_lookup_channel): Ditto.

2022-08-28  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/gblender.c (gblender_lookup): Quest for perfect hash function.

2022-08-28  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Minor fixes.

	(gblender_clear): Initialize with black background, whereas
	foreground stays invalid.
	(gblender_lookup_channel): Increase cache utilization.

2022-08-26  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Slight optimization of cached gradients.

	This saves about 1% of `ftgrid` execution time.

	* graph/gblender.c (gblender_reset_key, gblender_reset_channel_key):
	Implement faster gradients, which are rounded anyway.

2022-08-25  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Rework cache management.

	With more complex rendering in `ftgrid`, the old cache management
	resulted in excessive clashes and slow `gblender_lookup`.  It is
	better to replace the clashing entries than to preserve them and
	search for an available spot in the table.  This saves about 10%
	of execution time in `ftgrid` without much effect on the others.

	* graph/gblender.c (gblender_lookup): Replace old clashing entries
	and hash function.
	(gblender_lookup_channel): Ditto.
	* graph/gblender.h (GBlenderRec): Remove `stat_clears`.

2022-08-25  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/gblender.c (gblender_lookup*): Count clashes directly.

2022-08-23  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Count the number of hash clashes.

	The hash table lookups take very noticeable time when rendering is
	complex like in `ftgrid`.  This can help optimize the hash function.

	* graph/gblender.h (GBLENDER_STATS): New field for clashes.
	* graph/gblender.c (gblender_init, gblender_lookup{,_channel},
	gblender_dump_stats): Initialize, collect, and report clashes.

2022-08-18  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Fix mishandling of LCDv formats.

	* graph/gblblit.c (gblender_blit)init): Triple the LCDv pitch.

2022-08-17  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/gblender.c: Minor.

2022-08-17  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/gblblit.c (grBlitGlyphToSurface): Remove redundant check.

	* graph/gblender.c (gblender_set_gamma_table): Reintroduce linear loops.

2022-08-17  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/gblender.c (gblender_set_gamma_table): Updated sRGB ramps.

	When we use finite approxination it is more appropriate to use the
	actual values for the linear portion instead of the standard ones.

2022-08-16  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/common.c (utf8_next): Use more efficient algorithm.

2022-08-11  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftcommon.c (FTDemo_Draw_Header): Show non-trivial face index.

	This is a useful hint if a file contains multiple faces.

2022-08-07  Alexei Podtelezhnikov  <apodtele@gmail.com>

	(grid_status_draw_outline): Handle errors in `FT_Get_Glyph`.

2022-07-11  Charlie Jiang  <w@chariri.moe>

	[meson] Add option to disable librsvg dependency.

	As discussed in #14.

	Currently, 'librsvg' is used to render OT-SVG glyphs.  However, 'librsvg' is
	far from simple to build as it requires tons of transitive dependencies,
	especially on Windows.

	Therefore we introducee a configuration option to switch 'librsvg' on or
	off.  This is trivial because the source code itself already honors a
	`HAVE_LIBRSVG` macro.

	* meson_options.txt: Add `librsvg` option (feature), defaulting to
	`enabled`.

	* meson.build: Honor the option above.

	[ftview] Show empty charmaps if error, including UVS.

	* src/ftcommon.c (get_last_char): Call `FT_Set_Charmap` and handle
	its errors effectively setting `num_indices` to 0.
	* src/ftview.c (event_index_change, event_encoding_change): Updated.

2021-11-22  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* src/ftdump.c (Print_Charmaps): Do not iterate UVS charmaps.

2021-11-20  Werner Lemberg  <wl@gnu.org>

	* graph/*: Fix clang compilation warnings.

	Add casts for signed vs. unsigned issues.

2021-11-20  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[ftview] Report the last shown index or charcode.

	Together with the index or charcode limit, it gives a sense of the
	portion of the font under review.  This is reported at the bottom-
	left corner.

	* src/ftview.c (main): Pass the last shown index instead of error.
	(Render_*): Return the last shown index, charcode, or -1.
	(write_header): Receive and display the last shown index or charcode.

	[ftview] Report the last available index or charcode.

	* src/ftcommon.c (get_last_char): Implement the binary search for
	the last charcode using `FT_Get_Next_Char`.
	(FTDemo_Set_Current_Font): Set the number of indices accordingly.
	* src/ftview.c (write_header): Display the last charcode or index.

2021-11-17  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Complete removal of legacy blitter.

	This switches the remaing monochrome rendering of headers to the main
	blender and deletes the legacy blitter. The old blitter can handle
	exotic target surfaces like monochrome or 4-bit bitmaps. Anything
	beyond the alpha blender can do.

	* graph/grfont.c (grWriteCellChar, grWriteCellString): Switch from
	`grBlitGlyphToBitmap` to `grBlitGlyphToSurface`.
	* graph/grblit.[ch]: Delete files.
	* graph/graph.h, graph/grconfig.h: Remove references.
	* graph/rules.mk, graph/meson.build, vms_make.com,
	builds/windows/msvc/migs.vcxproj: Update build scripts.

2021-11-15  Werner Lemberg  <wl@gnu.org>

	* src/*: Fix clang warnings.

	All of them are minor and belong to one of the following categories:

	* signedness casts
	* corrected `printf` signatures
	* missing `static` keyword for local functions

2021-11-15  Werner Lemberg  <wl@gnu.org>

	[ftbench] Fix clang warnings.

	* src/ftbench.c (first_index, last_index): Make these two global variables
	signed, to be of the same type as `incr_index` (which can be positive or
	negative).
	Update all related code.

2021-11-15  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/win32/grwin32.c (gr_win32_surface_set_icon): Add background.

	[builds/windows] New project and solution files.

	These files can be used to build selected FreeType demo programs
	using Microsoft Visual C++. FreeType should be compiled in the
	parallel folder with freetype.lib available in freetype\objs\
	for compilation.  The executables will be delivered into
	freetype-demos\bin\ and expect freetype.dll there as well.

	* builds/windows/msvc/ft2demos.sln: Solution file.
	* builds/windows/msvc/*.vcxproj: Project files.

2021-10-26  Alexei Podtelezhnikov  <apodtele@gmail.com>

	FT2_BUILD_LIBRARY unnecassary in most cases.

	* src/ftinspect/ftinspect.pro: Ditto.

2021-10-23  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* graph/grdevice.c (grWriteSurface{Char,String}): Use GR_FONT_SIZE.

2021-10-18  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[graph] Do not zero a new bitmap.

	The `grNewBitmap` function is mostly used to allocate and resize
	canvas, which is shortly flooded with a background color.  There is
	no need to zero it.

	* graph/grobjs.c (grNewBitmap): Always call `realloc` directly,
	which does not initialize the buffer.
	* graph/grobjs.c (grNewBitmap): Update description.
