+
+ Doing so allows us to link them to edges \96 some fonts like
+ `NotoSansGurmukhi-Regular' have such isolated points sitting exactly
+ on other outlines.
+
+ * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't
+ ignore one-point contours but handle them specially as one-point
+ segments.

+ This patch restores original `TCoord' definition as `int' so that the
+ rendering pool is used more efficiently on LP64 platforms (unix).
+
+ * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some
+ fields to `TCoord'.
+ (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline,
+ gray_sweep, gray_convert_glyph): Updated.
+
+2016-06-28 Alexei Podtelezhnikov <apodtele@gmail.com>

+ unsigned short.
+ Only reject `0xFFFF' as an invalid encoding offset.
+
+2016-06-25 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Really fix deallocation in case of error (#47726).
+

+ `outline.points' also.
+
+2016-06-23 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Consolidate memory management.
+
+ * src/smooth/ftgrays.c (gray_init_cells): Remove function.
+ (gray_TWorker): Remove fields that become local variables.
+ (gray_raster_render): Move rendering buffer declaration from here.
+ (gray_convert_glyph): ... to here and update accordingly.
+
+2016-06-22 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Consolidate boundary checks.
+
+ Removing the checks from `gray_hline' shaves 1% off rendering speed.
+
+ * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'.
+ (gray_TWorker): No need to store `clip_box'.
+ (gray_hline): Remove unnecessary boundary checks.
+ (gray_convert_glyph): Move boundary checks from here.
+ (gray_raster_render): ... to here and consolidate.
+
+2016-06-21 Alexei Podtelezhnikov <apodtele@gmail.com>

+
+2016-06-18 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Remove `band_shoot' that never worked.
+
+ * src/smooth/ftgrays.c (gray_TWorker): Remove `band_shoot'.
+ (gray_convert_glyph): Updated.
+
+2016-06-17 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [raster, smooth] Handle FT_RENDER_POOL_SIZE better.

+
+2016-06-09 David Capello <davidcapello@gmail.com>
+
+ [cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files.
+
+ * CMakeLists.txt: Each time cmake is run those files are
+ modified and the whole FreeType library is recompiled. With this
+ change we change the files only if there are real modifications, so
+ we can avoid recompilations.
+
+2016-06-09 Werner Lemberg <wl@gnu.org>
+
+ [bdf] Check number of properties (#48166).
+
+ * src/bdf/bdflib.c (_bdf_parse_start): Implement.
+
+2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Re-enable new line renderer on 64-bit archs.
+
+ * src/smooth/ftgrays.c (gray_render_line): Conditionally re-enable new

+
+2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Minor clean-ups.

+
+ * src/autofit/afstyles.h: Add Ethiopic data.
+
+2016-06-07 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix compilation with VS2016 (#48126).
+
+ This compiler doesn't recognize the end-of-comment sequence `*/' if
+ it immediately follows non-ASCII characters.
+
+ * src/autofit/afscript.h: Ensure whitespace before `*/'.
+
+2016-06-04 Werner Lemberg <wl@gnu.org>
+
+ Fix a test for named instances (#48122).
+
+ This was missed while giving negative face indices an extended
+ meaning.
+
+ * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.
+
+2016-05-31 Nikolaus Waxweiler <madigens@gmail.com>
+
+ [truetype] Let SHPIX move points in the twilight zone in v40.
+
+ * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
+ the twilight zone. Otherwise, treat SHPIX the same as DELTAP.
+ Unbreaks various fonts such as older versions of Rokkitt and DTL
+ Argo T Light that would glitch severly after calling ALIGNRP after a
+ blocked SHPIX.
+
+2016-05-30 Werner Lemberg <wl@gnu.org>
+
+ [type42] Support `CharStrings' entry format as created by LilyPond.
+
+ * src/type42/t42parse.c (t42_parse_charstrings): Handle entries
+ having the format
+
+ (foo) cvn 12345 def
+
+2016-05-28 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
+
+ Suggested by Alexei. `UL' is only needed for 16bit compilers, but
+ it seems noone is using this anymore (and we no longer test whether
+ FreeType compiles in such an environment). Otherwise, it is easy to
+ add the postfix to the `AF_UNICODE_RANGE' macro.
+
+2016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Shrink bisection stack.
+
+ The convergence of Bézier flatteners is fast with the deviation
+ from straight line being assymptotically cut 4-fold on each bisection.
+ This justifies smaller bisection stack size.
+
+ * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
+ (gray_render_conic): Create and use conic `bez_stack'. Move back the
+ band analysis from...
+ (gray_conic_to): ... here.
+ (gray_render_cubic): Create and use cubic `bez_stack'. Move back the
+ band analysis from...
+ (gray_cubic_to): ... here.
+ (gray_move_to): Updated.
+
+2016-05-25 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fixes for Armenian and Gujarati ranges.
+
+ * src/autofit/afranges.c (af_armn_uniranges): Corrected.
+ (af_guru_nonbase_uniranges): Make U+0A3E a base character.
+
+2016-05-24 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add support for Armenian script.
+
+ * src/autofit/afblue.dat: Add blue zone data for Armenian.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Armenian standard characters.
+
+ * src/autofit/afranges.c: Add Armenian data.
+
+ * src/autofit/afstyles.h: Add Armenian data.
+
+2016-05-23 Werner Lemberg <wl@gnu.org>
+
+ * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
+
+ This was commented about 10 years ago \96 I think the reason then to
+ disable libtool's `-export-symbols' option was to give some badly
+ programmed applications access to internal FreeType functions.
+
+ I believe that we should no longer take care of such programs; the
+ number of symbols exported should be rather restricted as much as
+ possible.
+
+2016-05-22 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add blue-zone support for Gurmukhi script.
+
+ This essentially moves the Gurmukhi script from the `Indic' hinter to
+ the `Latin' hinter.
+
+ * src/autofit/afblue.dat: Add blue zone data for Gurmukhi.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Gurmukhi standard characters and move
+ data out of AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afranges.c: Move Gurmukhi data out of
+ AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
+ AF_WRITING_SYSTEM_LATIN.
+
+2016-05-21 Werner Lemberg <wl@gnu.org>
+
+ Minor clang++ fixes.
+
+ * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c
+ (ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add
+ initializer.
+
+ * src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit
+ conversion from NULL to boolean.
+
+2016-05-21 Werner Lemberg <wl@gnu.org>
+
+ Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955).
+
+ * include/freetype/internal/ftmemory.h (cplusplus_typeof): Use
+ braces for `extern "C++"'.
+
+2016-05-17 Nikolaus Waxweiler <madigens@gmail.com>
+
+ [truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3].
+
+ * src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with...
+ (tt_loader_set_pp): ... this new function.
+ Update all callers.
+
+2016-05-17 Nikolaus Waxweiler <madigens@gmail.com>
+
+ [truetype] New implementation of v38 bytecode interpreter [2/3].
+
+ This patch actually modifies the bytecode interpreter.
+
+ See added comments in `ttinterp.h' for more information on this and
+ the following commit in the series.
+
+ * src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by...
+ (NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY,
+ SUBPIXEL_HINTING_MINIMAL): ...new macros.
+ (Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backwards
+ compatibility.
+ Updated.
+ (Ins_RS, Ins_FDEF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_MD):
+ Updated.
+ (Ins_INSTCTRL): Handle native ClearType mode flag.
+ Updated.
+ (Ins_FLIPPT, Ins_FLIPRGON, Ins_FLIPRGOFF): Handle backwards
+ compatibility.

+
+ [truetype] New implementation of v38 bytecode interpreter [1/3].
+
+ This patch prepares data structures and the like.
+
+ See added comments in `ttinterp.h' for more information on this and
+ the following commits in the series.
+
+ * devel/ftoption.h, include/freetype/config/ftoption.h
+ (TT_CONFIG_OPTION_SUBPIXEL_HINTING): Assign values to differentiate
+ between subpixel versions.
+ (TT_SUPPORT_SUBPIXEL_HINTING_INFINALITY,
+ TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL): New macros.
+
+ * include/freetype/ftttdrv.h (TT_INTERPRETER_VERSION_40): New macro.
+
+ * include/freetype/internal/tttypes.h (TT_FaceRec): Updated.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): Define new fields
+ `subpixel_hinting_lean', `vertical_lcd_lean',
+ `backwards_compatibility', `iupx_called', iupy_called', and
+ `grayscale_cleartype' for new hinting mode.
+
+ * src/truetype/ttdriver.c (tt_property_set): Handle v38 and v40
+ interpreters conditionally.
+
+ * src/truetype/ttgload.c (TT_Hint_Glyph): Save phantom points unless
+ in v38 backwards compatibility mode.
+ Updated.
+ (compute_glyph_metrics): Add v38 backwards compatibility mode
+ constraint for adjusting advance widths.
+ Updated.

+ Updated.
+
+ * src/truetype/ttobjs.c (tt_driver_init): Conditionally set
+ default interpreter version number.
+
+ * src/truetype/ttsubpix.c, src/truetype/ttsubpix.h: Updated.
+
+2016-05-17 Werner Lemberg <wl@gnu.org>
+
+ [cff] Fix matrix scaling (#47848).
+
+ * include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro.
+
+ * src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling
+ value of all matrix coefficients to scale matrix.
+
+ * src/cff/cffobjs.c (cff_face_init): Use `matrix->yx' member for
+ matrix normalization if `matrix->yy' is zero.
+
+2016-05-16 Werner Lemberg <wl@gnu.org>
+
+ [base] Reject invalid sfnt Mac resource (#47891).
+
+ * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Check validity
+ of `CID ' and `TYPE1' table offset and length.
+
+2016-05-16 Werner Lemberg <wl@gnu.org>
+
+ [cid] Fix scanning for `StartData' and `/sfnts' (#47892).
+
+ * src/cid/cidparse.c (STARTDATA, STARTDATA_LEN, SFNTS, SFNTS_LEN):
+ New macros.
+ (cid_parser_new): Fix and document algorithm.
+
+2016-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [truetype] Improve the recursive reference detector.
+
+ The previous fix for #46372 misunderstood a composite glyph referring
+ same component twice as a recursive reference. See the discussion
+
+ http://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html
+
+ Thanks to Khaled Hosny for finding this issue.
+
+ * src/truetype/ttgload.c (ft_list_get_node_at): A function to get
+ the i-th node from FT_List.
+ (load_truetype_glyph): In the traversal scan of the reference tree
+ in the composite glyph, we clear the nodes filled by previous
+ sibling chain.
+
+2016-05-07 Werner Lemberg <wl@gnu.org>
+
+ [cache] Allow value 0 for face ID.
+
+ We never dereference `face_id', and some implementations might use a
+ running number instead of a pointer. Additionally, disallowing
+ value zero was undocumented.
+
+ * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c
+ (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for
+ `face_id'.
+
+2016-05-05 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] More efficient accounting of conic splits and draws.
+
+ A single decrement counter of segments to draw, instead of an array,
+ contains all the information necessary to decide when to split and
+ when to draw a conic segment. The number of splits before each draw is
+ equal to the number of trailing zeros in the counter.
+
+ * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.
+ (gray_render_conic): Updated to use decrement counter of segments.
+
+2016-05-05 Werner Lemberg <wl@gnu.org>
+
+ [cff, truetype] Fix logic for `FT_Property_Set'.
+
+ Otherwise some properties could be set to arbitrary values, which is
+ harmless, but querying could give wrong positive results.
+
+ * src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
+ * src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
+ Only allow defined values.
+
+2016-04-25 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add blue-zone support for Gujarati script.
+
+ This essentially moves the Gujarati script from the `Indic' hinter to
+ the `Latin' hinter.
+
+ * src/autofit/afblue.dat: Add blue zone data for Gujarati.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Gujarati standard characters and move
+ data out of AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afranges.c: Move Gujarati data out of
+ AF_CONFIG_OPTION_INDIC block.
+
+ * src/autofit/afstyles.h: Update Gujarati data; in particular, use
+ AF_WRITING_SYSTEM_LATIN.
+
+2016-04-24 Werner Lemberg <wl@gnu.org>
+
+ Minor.
+
+ * include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Protect macro
+ argument with parentheses.
+
+2016-04-24 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix deallocation in case of error (#47726).
+
+ * src/truetype/ttgload.c (load_truetype_glyph): Initialize fields in

+
+2016-04-23 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Improve Georgian blue zone characters.
+
+ Suggested by Akaki Razmadze <razmadzekoko@gmail.com>.
+
+ * src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM):
+ Updated.
+
+ * src/autofit/afblue.c: Regenerated.
+
+2016-04-16 David Capello <davidcapello@gmail.com>
+
+ [cmake] Honor SKIP_INSTALL_* settings (as used in zlib).
+
+ As FreeType depends on zlib, if we don't install zlib (e.g., because
+ we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too
+ (cmake triggers an error saying that FreeType cannot be installed
+ because zlib target isn't in the export set).
+
+ * CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS',
+ `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings.
+
+2016-04-16 Behdad Esfahbod <behdad@behdad.org>
+
+ [truetype] Another fix for non-intermediate GX tuples.
+
+ * src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing
+ cases.
+
+2016-04-12 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ Remove forgotten macro.
+
+ * include/freetype/internal/internal.h
+ [FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove.
+
+2016-04-09 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add support for Georgian scripts.
+
+ Georgian is problematic, since `uppercase' forms of Mkhedruli
+ (called Mtavruli) are not yet defined in Unicode, which means that
+ proper blue zones can't be defined. However, there is already a
+ proposal submitted to Unicode; see
+
+ http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+
+ Additionally, due to historical reasons, Unicode treats Khutsuri as
+ the same script as Mkhedruli, and so does OpenType. However, since
+ the two scripts have completely different shapes it can happen that
+ blue zones differ considerably. The tag `geok' used here (derived
+ from ISO 15924) to differentiate the two scripts is not an OpenType
+ tag in use. If we now have a font that contains both glyphs for
+ Mkhedruli and Khutsuri, and it uses OpenType features for both also,
+ HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
+ blue zones for `geok' are not used for glyphs involved in the
+ OpenType features.
+
+ An issue not yet resolved is which OpenType feature should be used
+ to access Mtavruli glyph shapes; right now, FreeType doesn't set up
+ support for them, but it is easy to add them later on as soon as
+ more information is available.

+ * version.
+ *
+ * TT_INTERPRETER_VERSION_40 ::
+ * Version~40 corresponds to MS rasterizer v.2.1; it is roughly
+ * equivalent to the hinting provided by DirectWrite ClearType (as can
+ * be found, for example, in Microsoft's Edge Browser on Windows~10).
+ * It is used in FreeType to select the `minimal' subpixel hinting
+ * code, a stripped-down and higher performance version of the
+ * `Infinality' code.
*
* @note:
* This property controls the behaviour of the bytecode interpreter
* get rasterized! In particular, it does not control subpixel color
* filtering.
*
- * If FreeType has not been compiled with configuration option
- * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
- * `FT_Err_Unimplemented_Feature' error.
+ * If FreeType has not been compiled with the configuration option
+ * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+ * an `FT_Err_Unimplemented_Feature' error.
*
* Depending on the graphics framework, Microsoft uses different
* bytecode and rendering engines. As a consequence, the version
* the version~1 gasp table exclusively (like Color ClearType), while
* v1.6 only respects the values of version~0 (bits 0 and~1).
*
- * FreeType doesn't provide all capabilities of the most recent
- * ClearType incarnation, thus we identify our subpixel support as
- * version~38.
+ * Keep in mind that the features of the above interpreter versions
+ * might not map exactly to FreeType features or behavior because it is
+ * a fundamentally different library with different internals.

+ * Modern TrueType fonts are usually rendered through Microsoft's
+ * collection of rendering techniques called ClearType (e.g., subpixel
+ * rendering and subpixel hinting). When ClearType was introduced, most
+ * fonts were not ready. Microsoft decided to implement a backwards
+ * compatibility mode that employed several simple to complicated
+ * assumptions and tricks that modified the interpretation of the
+ * bytecode contained in these fonts to make them look ClearType-y
+ * somehow. Most (web)fonts that were released since then have come to
+ * rely on these hacks to render correctly, even some of Microsoft's
+ * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
+ *
+ * The minimal subpixel hinting code (interpreter version 40) employs a
+ * small list of font-agnostic hacks to bludgeon non-native-ClearType
+ * fonts (except tricky ones[1]) into submission. It will not try to
+ * toggle hacks for specific fonts for performance and complexity
+ * reasons. The focus is on modern (web)fonts rather than legacy fonts
+ * that were made for black-and-white rendering.
+ *
+ * Major hacks
+ *
+ * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+ * `Direct_Move_X'). This has the smallest code footprint and single
+ * biggest effect. The ClearType way to increase resolution is
+ * supersampling the x axis, the FreeType way is ignoring instructions
+ * on the x axis, which gives the same result in the majority of
+ * cases.
+ *
+ * - Points are not moved post-IUP (neither on the x nor on the y axis),
+ * except the x component of diagonal moves post-IUP (cf.
+ * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
+ * changes are commonly used to `fix' pixel patterns which has little
+ * use outside monochrome rendering.
+ *
+ * - SHPIX and DELTAP don't execute unless moving a composite on the
+ * y axis or moving a previously y touched point. SHPIX additionally
+ * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+ * Both instructions are commonly used to `fix' pixel patterns for
+ * monochrome or Windows's GDI rendering but make little sense for
+ * FreeType rendering. Both can distort the outline. See [2] for
+ * details.
+ *
+ * - The hdmx table and modifications to phantom points are ignored.
+ * Bearings and advance widths remain unchanged (except rounding them
+ * outside the interpreter!), cf. `compute_glyph_metrics' and
+ * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
+ * might mess up spacing.
+ *
+ * Minor hacks
+ *
+ * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
+ * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+ * various sizes.
+ *
+ * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+ * executed.)
+ *
+ * The best results are achieved for fonts that were from the outset
+ * designed with ClearType in mind, meaning they leave the x axis mostly
+ * alone and don't mess with the `final' outline to produce more
+ * pleasing pixel patterns. The harder the designer tried to produce
+ * very specific patterns (`superhinting') for pre-ClearType-displays,
+ * the worse the results.
+ *
+ * Microsoft defines a way to turn off backwards compatibility and
+ * interpret instructions as before (called `native ClearType')[2][3].
+ * The font designer then regains full control and is responsible for
+ * making the font work correctly with ClearType without any
+ * hand-holding by the interpreter or rasterizer[4]. The v40
+ * interpreter assumes backwards compatibility by default, which can be
+ * turned off the same way by executing the following in the control
+ * program (cf. `Ins_INSTCTRL').
+ *
+ * #PUSH 4,3
+ * INSTCTRL[]
+ *
+ * [1] Tricky fonts as FreeType defines them rely on the bytecode
+ * interpreter to display correctly. Hacks can interfere with them,
+ * so they get treated like native ClearType fonts (v40 with
+ * backwards compatibility turned off). Cf. `TT_RunIns'.
+ *
+ * [2] Proposed by Microsoft's Greg Hitchcock in
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+ *
+ * [3] Beat Stamm describes it in more detail:
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
+ *
+ * [4] The list of `native ClearType' fonts is small at the time of this
+ * writing; I found the following on a Windows 10 Update 1511
+ * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+ * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+ * SimSun, NSimSun, and Yu Gothic.
