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.

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.

254933c397 When sanitizing, delay making writable 
Before, as soon as we needed to make an edit, we tried to make the blob
writable inplace.  That grows code unnecessarily though.  We can simply
fail, make writable, then start again.  That's indeed what the fallback
was doing anyway.

a065f471b3 Cleanup Extension lookups 
Two things:

1. Allow nested Extension lookups.  The offset is always positive, so
it can't loop circularly.

2. Move the check for all Extension subtables having the same lookup
type to the correct place.  Before it wasn't really working.
