to be fetched properly.

4816be9ab5 Work around cairo limitations 
If we just draw an image, cairos recording surface
complains that it is unbounded. Its not true of course.

To make things work, clip to the extents.

56a48f8b0a [paint] Don't use extents in hb-view 
Let the clipbox do its magic. Currently works for ft backend only.

ecd7420456 Debug spew 
To get a dump of the hb-paint callbacks,
set HB_PAINT_DEBUG=1 when running hb-view.

For now, leave this code in place, since it
comes in handy for various debugging.

381d410b1e [paint] Add HB_PAINT_IMAGE_FORMAT_BGRA and use it in hb-ft 
Now hb-ft can render color emoji as well.

Just left COLRv2.

6387004cad [paint] Simplify api

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.

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.

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.

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.
