II. IMPORTANT CHANGES

|

- Face metrics (face->size->metrics) and glyph metrics are no
|
||||
longer rounded. If you do not round in your applications too,
|
||||
you may find glyphs become blurry.
|
||||
|
||||
- A new API `FT_TrueTypeGX_Validate' (in FT_GX_VALIDATE_H) has
|
||||
been added to validate TrueType GX/ATT tables (feat, mort, morx,
|
||||
bsln, just, kern, opbd, trak, prop). After validation it is no
