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 a 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.

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. + +2016-04-05 Werner Lemberg <wl@gnu.org> + + [autofit] Provide dummy blue zone for pseudo script `none'. + + Even if the dummy hinter is used as the handler for `none' (which + doesn't use blue zones), it is more consistent than the old value + (which was 0), pointing to Arabic... + + * src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'. + * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. + + * src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE. + +2016-03-30 Werner Lemberg <wl@gnu.org> + + * src/pfr/pfrload.c (pfr_aux_name_load): Thinko (#47567). + +2016-03-30 Werner Lemberg <wl@gnu.org> + + * src/pfr/pfrload.c (pfr_log_font_count): Better font size estimate. + +2016-03-30 Werner Lemberg <wl@gnu.org> + + * src/pfr/pfrload.c (pfr_aux_name_load): Fix memory leak (#47567). + +2016-03-29 Werner Lemberg <wl@gnu.org> + + * src/base/ftadvanc.c (FT_Get_Advances): Fix invalid left shift. + +2016-03-29 Werner Lemberg <wl@gnu.org> + + [pfr] Fix binary search (#47514). + + * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Handle border + conditions correctly. + +2016-03-29 Werner Lemberg <wl@gnu.org> + + [pfr] Minor. + + * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Replace `left', + `right', and `middle' with `min', `max', and `mid' as used in other + FreeType binary search code. + (pfr_load_bitmap_metrics): Fix invalid left shift. + +2016-03-29 Werner Lemberg <wl@gnu.org> + + * src/pfr/pfrtypes.h: Replace all enums with macros. + + We need `~FOO' to unset bits, and only with unsigned values (which + `enum' isn't normally) this works cleanly. + +2016-03-26 Werner Lemberg <wl@gnu.org> + + [pfr] Robustify bitmap strike handling (#47514). + + We did a binary search for a charcode without ensuring that the + searched data is ordered.
