- * In general, this file does a fine job of what it's supposed to do.
- * There are, however, things that need more work:
- *

-- * I believe hb_ft_font_create() should take load_flags input.
-- * In particular, FT_Get_Advance() without the NO_HINTING flag seems to be
-- * buggy.
-+ * - I remember seeing FT_Get_Advance() without the NO_HINTING flag to be buggy.
-+ * Have not investigated.
-+ *
-+ * - FreeType works in 26.6 mode. Clients can decide to use that mode, and everything
-+ * would work fine. However, we also abuse this API for performing in font-space,
-+ * but don't pass the correct flags to FreeType. We just abuse the no-hinting mode
-+ * for that, such that no rounding etc happens. As such, we don't set ppem, and
-+ * pass NO_HINTING as load_flags. Would be much better to use NO_SCALE, and scale
-+ * ourselves, like we do in uniscribe, etc.
- *
