2010-05-20 14:05:02 +01:00
Behdad Esfahbod 009aad5678 Invert the mask logic
Before, the mask in the buffer was inverted.  That is, a 0 bit meant
feature should be applied and 1 meant not applied, whereas in the
lookups, the logic was positive.

Now both are in sync.  When calling hb_buffer_add_glyph() manually,
the mask should be 1 instead of 0.

Behdad Esfahbod 0a4399ca22 Fix scale issues
hb_font_set_scale() now sets the value to be used to represent a unit
pixel.  For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6).  For 10px in 16.16 you would set it to
(10 << 16).  This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.
