It was broken all this time :(.

The two backends do this slightly differently...

To make sure we don't accidentally forget to_float().

Behdad Esfahbod d045de78c1 [paint] Optimize PAINT_COMPOSITE
At the start of each paint call the current group is clear.
So we don't need to start a new group for the backdrop paint.

A paint composite really needs one group push, not two.

Drop the hb_paint_context_t struct from the API, and

Matthias Clasen 71bd5a0dfc [paint] Resolve colors
We don't need to pass the index/alpha pairs to
client callbacks, and can just resolve the colors
internally.

Update test results.

Matthias Clasen 9be01b6bff [paint] Pass hb_paint_context_t along
Replace the font argument with a hb_paint_context_t
that carries the font, the palette index and the
foreground color.

The hb_font_paint_glyph() api now takes the palette
index and the foreground color as extra arguments.

Update all callers and regenerate test results.

Matthias Clasen 97224f3b63 [paint] Pass font to all callbacks
This will lead to easier implementations.

At the same time, we change the push_clip_glyph
callback to use the font as-is, no unscaling needed.

Update all callers and expected test results.
