Behdad Esfahbod 383060cc33 [ft] Invalidate advance cache if font size changed 2018-09-11 14:41:19 +02:00
Behdad Esfahbod 54998befc4 [ft] Cache advances 
I decided to always use the cache, instead of my previous sketch direction
that was to only allocate and use cache if fast advances are not available.
The cache is a mere 1kb, so just use it...

TODO: Invalidate cache on font size change.

Behdad Esfahbod 93f7c1652a Revert "[glib/ucdn/icu/ft/ot] Make returned funcs inert" 
This reverts commit 5daf3bd449.

If other atexit callbacks try to destruct the objects we destruct
in atexit callbacks, bad things will happen.

I'll come up with some other way to catch premature destruction
of HB-owned objects.

Behdad Esfahbod 4e4781319b [ft] Add hb_ft_font_changed() 
When the font size or variations settings on underlying FT_Face change,
one can call hb_ft_font_changed() and continue using hb_font created using
hb_ft_font_create().

Behdad Esfahbod 333173103b Fix sign of shift operators 
This one:

  map->mask = (1 << (next_bit + bits_needed)) - (1 << next_bit);

before the fix, the shift was done as an int, causing overflow
if it ever got to 1 << 31.  Sprinkle 'u's around.

Birunthan Mohanathas 6bf9db4f1e [ft] Fix unsafe cast of FT_Done_Face in hb_ft_{face,font}_create_referenced (#289) 
Prior to this change the function `FT_Error FT_Done_Face(FT_Face *)` was
called through a pointer with the signature `void (void *)` resulting in
undefined behaviour.

Behdad Esfahbod 8b5bc141cd Add get_nominal_glyph() and get_variation_glyph() instead of get_glyph() 
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.

Behdad Esfahbod ca97ea7aa2 [ft] Revert change-of-behavior of hb_ft_font_create() introduced in 1.0.5 
The default FreeType load flags where changed from FT_LOAD_NO_HINTING
to FT_LOAD_DEFAULT in 2a9627c564.
This is crashing HarfBuzz-enabled FreeType as I suppose it causes
infinite recursion between HB and FT autohinter...

Revert the behavior change.
