Behdad Esfahbod 744970af4d [API] Add support for vertical text
Design not final yet, and in fact I'm going to change it immediately,
but this is an standalone change for itself.

Behdad Esfahbod f7acd8df51 Do alternate glyph selection!
Kinda hand-wavy right now.  Not tested.

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.
