src/autofit/autofit.c: Adding experimental implementation of `warp
|

hinting' (new hinting algorithm for gray-level and LCD rendering).
|

It is disabled by default, you need to #define AF_USE_WARPER in

aftypes.h to enable it.

|
||||
New function.
|

* src/autofit/afhints.h: Updated.
|
||||
|
||||
* src/autofit/aflatin.c [AF_USE_WARPER]: Include afwarp.h.
|

(af_latin_hints_init) [AF_USE_WARPER]: Reset mode to
|
||||
FT_RENDER_MODE_NORMAL if an LCD mode is selected.
|
||||
(af_latin_hints_apply) [AF_USE_WARPER]: Call af_warper_compute
|
||||
appropriately.
|
||||
|
||||
* src/autofit/afloader.c (af_loader_load_g) [!AF_USER_WARPER]:
|
||||
Isolate code for adjusting metrics.
|
||||
|
||||
* src/autofit/aftypes.h (AF_USE_WARPER): New macro (commented out by
|
||||

|
||||
|
||||
* src/autofit/afwarp.c, src/autofit/afwarp.h: New files.
