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.

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.

index and the foreground color as extra arguments.
