[ftrandom] Improve Makefile. It now supports both a normal build (`./configure && make') and a development build (`make devel'). * src/tools/ftrandom/Makefile (VPATH): Set it so that `libfreetype.a' gets searched in both `objs' (for the development build) and `objs/.libs' (for a normal build which uses libtool). (LIBS): Add missing libraries. (ftrandom.o): New rule. (ftrandom): Use automatic variables.

[smooth] Simplify span rendering more. It turns out that there is significant cost associated with `FT_Span' creation and calls to `gray_render_span' because it happerns so frequently. This removes these steps from our internal use but leaves it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain is about 5%. * src/smooth/ftgrays.c (gray_render_span): Removed.

[smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol.

Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol.

* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'. This was commented about 10 years ago – 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.

[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. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data.

[autofit] Fix handling of default script.
Patch taken from ttfautohint, commit
071ae2c00e0d67f9d19418f4fade1c23d27dc185.
There were two bugs.
- We now use non-standard script tags like `khms' for special
purposes. However, HarfBuzz maps such tags to `DFLT', and
without this commit the associated lookups were incorrectly
assigned to the non-standard tags.
- Let's assume we have a Bengali font, and the font's `DFLT'
script tag handles the necessary lookups for Bengali, too.
Without this commit, the `DFLT' lookups were assigned to
ttfautohint's default script (usually `latn') before the
standard lookups for Bengali were handled.
We now have the following order while searching for covered
glyph indices.
special features of scripts (e.g. `sups' for Cyrillic)
Unicode mappings of scripts
remaining features of scripts (especially important for Indic
scripts)
default features of default script
* src/autofit/afshaper.c, src/autofit/afshaper.h
(af_shaper_get_coverage): Add boolean parameter to indicate default
script.
Update all callers.
* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
Fix search order for coverages.

[smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.

[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.

This commit adds two fallback scripts (`latb', `latp') and
implements support for the no-base character ranges introduced in
the previous commit.

* src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and

* src/autofit/afblue.dat: Add blue zones for Latin subscript and
superscript fallback scripts.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base
characters.

* src/autofit/afglobal.c (SCRIPT): Updated.

* src/autofit/aflatin.c (af_latin_hints_apply): Handle new style
flag.
* src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.
[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.

[cache] Replace `FT_PtrDist' with `FT_Offset'. * src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t') is a better choice for `hash' to hold a pointer than `FT_PtrDist' (a.k.a. `ptrdiff_t'), especially since the latter is signed, causing zillions of signedness warnings. [Note that `hash' was of type `FT_UInt32' before the change to `FT_PtrDist.] Update all users. * src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcglyph.c, src/cache/ftcglyph.h: Updated.

[raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round).

[raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it).

[raster] Remove 5-level gray AA mode from monochrome rasterizer. The value of FT_RENDER_POOL_SIZE still serves the purpose it used to serve, which is, to adjust the pool size.
