Behdad Esfahbod 81bf089273 [hb-view] Use color render callback if HB_DRAW >= 2 2022-12-23 13:37:59 -07:00
Matthias Clasen c65f580b93 Drop hb-test
This was a test binary to assist in developing
the hb-paint code. Not needed anymore, now that
hb-view has the same code in the cairo userfont
backend.

Behdad Esfahbod 95ccd66481 [hb-view] Set glyph extents in render_color_glyph
