Matthias Clasen 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.

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

Matthias Clasen 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.

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.

This was double-slanting with hb-draw, and not slanting without it.

Behdad Esfahbod da500568de [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph
Instead of using gid=0 when a character is not found in the font,
client can now set a custom value.  This is useful for shaper-driven
font fallback and to differentiate that from .notdef glyph.

Garret Rieger 1e1438c4fb
[subset] fix --*-file options in hb-subset. (#3176)
The previous change to add -/+ versions of each set type broke all of the --*-file input options since all of the parse functions now default to replacing the set if the + variant is not being used. This fixes the issue by changing parse_file_for to pass '+' as the name to the parsing function. This triggers the append mode.

Instead use inverted sets to handle requesting all features. Modifies feature collection in subset plan to intersect the set of requested features against the features in the font. This prevents iterating a fully filled feature tag set.
