Behdad Esfahbod 71d52e10aa [var] Fix getting side-bearing variations
In HVAR/VVAR, if the side-bearing mappings are null, it means the
table does not have them and they should be loaded from glyf table.
Previous logic was returning zer0.

Behdad Esfahbod 13c499cb26 [hvar] Minor internal rewiring
Not passing font to functions makes it more clear that they don't
scale values.

Behdad Esfahbod e062376ef1 [machinery] Make accelerator lazy-loader call Xinit/Xfini
Instead of init/fini. To isolate those functions. To be turned into
constructor/destructors, ideally one per commit (after some SFINAE
foo.)

Behdad Esfahbod 53eebc7cd2 [CONFIG] Add HB_NO_VERTICAL 2021-12-08 08:34:20 -08:00
Garret Rieger b14475d2ae [subset] further changes to serializer error handling.
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.
2021-03-18 10:51:26 -07:00
Garret Rieger 73ed59f7a6 [subset] store errors in the serializer as a flag set.
Make check_assign/check_equal specify the type of error to set.
