2016-02-24Add get_nominal_glyph() and get_variation_glyph() instead of get_glyph()Behdad Esfahbod13-91/+344
New API: - hb_font_get_nominal_glyph_func_t - hb_font_get_variation_glyph_func_t - hb_font_funcs_set_nominal_glyph_func() - hb_font_funcs_set_variation_glyph_func() - hb_font_get_nominal_glyph() - hb_font_get_variation_glyph() Deprecated API: - hb_font_get_glyph_func_t - hb_font_funcs_set_glyph_func() Clients that implement their own font-funcs are encouraged to replace their get_glyph() implementation with a get_nominal_glyph() and get_variation_glyph() pair. The variation version can assume that variation_selector argument is not zero.

2016-02-24Partially revert 86c68c7a2c971efe8e35b1f1bd99401dc8b688d2Behdad Esfahbod2-17/+13
That commit moved the advance adjustment for mark positioning to be applied immediately, instead of doing late before. This breaks if mark advances are zeroed late, like in Arabic. Also, easier to hit it in RTL scripts since a single mark with non-zero advance is enough to hit the bug, whereas in LTR, at least two marks are needed. This reopens https://github.com/behdad/harfbuzz/issues/211 The cursive+mark interaction is broken again. To be fixed in a different way.

This better emulates Unicode grapheme clusters. Note that Uniscribe does NOT do this, but should be harmless with most clients, and improve fallback with clients that use HarfBuzz cluster as unit of fallback. Fixes https://github.com/behdad/harfbuzz/issues/217

Fixes https://github.com/behdad/harfbuzz/issues/223 Right now we cannot test this because it has to be tested using hb-fuzzer. We should move all fuzzing tests from test/shaping/tests/fuzzed.tests to test/fuzzing/ and have its own test runner. At that point, should add test from this issue as well.

2016-02-16[USE] Zero mark advances by GDEF earlyBehdad Esfahbod5-2/+5
This is what Microsoft's implementation does. Marks that need advance need to add it back using 'dist' or other feature in GPOS. Update tests to match.
2016-02-16[GPOS] Fix interaction of mark attachments and cursive chainingBehdad Esfahbod4-15/+18
Fixes https://github.com/behdad/harfbuzz/issues/211 What happens in that bug is that a mark is attached to base first, then a second mark is cursive-chained to the first mark. This only "works" because it's in the Indic shaper where mark advances are not zeroed. Before, we didn't allow cursive to run on marks at all. Fix that. We also where updating mark major offsets at the end of GPOS, such that changes in advance of base will not change the mark attachment position. That was superior to the alternative (which is what Uniscribe does BTW), but made it hard to apply cursive to the mark after it was positioned. We could track major-direction offset changes and apply that to cursive in the post process, but that's a much trickier thing to do than the fix here, which is to immediately apply the major-direction advance-width offsets... Ie.: https://github.com/behdad/harfbuzz/issues/211#issuecomment-183194739 If this breaks any fonts, the font should be fixed to do mark attachment after all the advances are set up first (kerning, etc). Finally, this, still doesn't make us match Uniscribe, for I explained in that bug. Looks like Uniscribe applies minor-direction cursive adjustment immediate as well. We don't, and we like it our way, at least for now. Eg. the sequence in the test case does this: - The first subscript attaches with mark-to-base, moving in x only, - The second subscript attaches with cursive attachment to first subscript moving in x only, - A final context rule moves the first subscript up by 104 units. The way we do, the final shift-up, also shifts up the second subscript mark because it's cursively-attached. Uniscribe doesn't. We get: [ttaorya=0+1307|casubscriptorya=0@-242,104+-231|casubscriptnarroworya=0@20,104+507] while Uniscribe gets: [ttaorya=0+1307|casubscriptorya=0@-242,104+-211|casubscriptnarroworya=0+487] note the different y-offset of the last glyph. In our view, after cursive, things move together, period.
