Behdad Esfahbod 60bf264ee2 [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). 
When points are not touched by gvar interpolation deltas, FreeType
gave a slightly different result than Apple's CoreText.

The OpenType working group will update the specification to document
the following behaviour: If the two points with deltas to the `left'
and `right' of the untouched point have the same coordinate, then
the inferred delta for the untouched point should be zero.

* src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new
behaviour.

 2017-04-26 11:40:28 +02:00
Werner Lemberg 5aa6716a5e Add new `slight' auto-hinting mode. 
This mode uses fractional advance widths and doesn't scale glyphs
horizontally, only applying vertical scaling and hinting.

At the same time, the behaviour of the `light' auto-hinter gets
restored for backwards compatibility: Both vertical and horizontal
scaling is again based on rounded metrics values (this was changed
in a commit from 2017-03-30 as a side effect).  To be more precise,
the behaviour is restored for TrueType fonts only; for other font
formats like Type 1, this is a new feature of the `light' hinting
mode.

* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
(FT_RENDER_MODE_SLIGHT): New render mode.

* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add
`autohint_mode' and `autohint_metrics' fields.

* src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c
(af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init):
Updated.

* src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use
`autohint_metrics'.
(af_loader_load_glyph): s/internal/slot_internal/.
Initialize `autohint_metrics' and `autohint_mode' depending on
current auto-hint mode.
Use `autohint_metrics'.
Updated.

* src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated.

* src/base/ftobjs.c (FT_Load_Glyph): Updated.
(FT_New_Size): Allocate `internal' object.

* src/pshinter/pshalgo.c (ps_hints_apply): Updated.

* src/smooth/ftsmooth.c (ft_smooth_render): Updated.

Werner Lemberg 5412d8869b Introduce `FT_Size_InternalRec' structure. 
We are going to extend this later on.

* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): New
structure with a single field `module_data'.

* src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of
`FT_Size' structure.

* src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use
`size->internal->module_data' instead of `size->internal'.

* src/cff/cffobjs.c (cff_size_done): Deallocate `module_data'.
(cff_size_init, cff_size_select, cff_size_request): Use
`size->internal->module_data' instead of `size->internal'.

* src/cif/cidobjs.c (cid_size_done, cid_size_init,
cid_size_request): Use `size->internal->module_data' instead of
`size->internal'.

* src/psaux/psobjs.c (t1_builder_ini): Use
`size->internal->module_data' instead of `size->internal'.

* src/type1/t1objs.c (T1_Size_Done, T1_Size_Init, T1_Size_Request):
Use `size->internal->module_data' instead of `size->internal'.
