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.

2022-12-23 13:37:59 -07:00
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.
2022-12-23 13:37:59 -07:00
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 will lead to easier implementations.

Update all callers and expected test results.

Matthias Clasen 2333a566ed Drop the deprecation
No need to drop hb_font_get_glyph_shape, just
because hb_font_draw_glyph does the same.

Its fine to keep both around.
2022-12-23 13:37:59 -07:00
Matthias Clasen 14b026ff86 [draw] Add hb_font_draw_glyph
hb_font_draw_glyph(), hb_font_draw_glyph_func_t and
hb_font_funcs_set_draw_glyph_func() are just alternative
names for hb_font_get_glyph_shape and friends, to better
align with hb_font_paint_glyph.

Matthias Clasen 0f287e75ec [paint] Rename hb_font_get_glyph_paint_func_t
The 'get' was just there due to implementation
choices. Work around that and call the vfunc
what it should be: hb_font_paint_glyph_func_t.

Matthias Clasen 0d890061d1 Rename 'solid' to 'color'
'solid' does not really describe well what
the function does, and there is no strong
reason to stick 1:1 to the terminology used
in the spec.

Nirbheek Chauhan 7be06f6377 meson: Override dependencies to improve usage as a subproject
With this change, harfbuzz can be consumed as a subproject without
making any changes to the build files of a project. All you need to do
is provide a wrap file with a `[provide]` section:

https://mesonbuild.com/Wrap-dependency-system-manual.html#provide-section

This is also necessary because otherwise projects need to hard-code
the subproject name, which might be `harfbuzz` when using `wrap-git` or
`harfbuzz-6.0.0` when using `wrap-file` (to build from a release
tarball). This can cause conflicts between different subprojects that
consume harfbuzz differently.

Other projects like glib, cairo, pango, etc already do this.
