Glyph paint callbacks.

The callbacks assume that the caller maintains a stack
of current transforms, clips and intermediate surfaces,
as evidenced by the pairs of push/pop callbacks. The
push/pop calls will be properly nested, so it is fine
to store the different kinds of object on a single stack.

Not all callbacks are required for all kinds of glyphs.
For rendering COLRv0 or non-color outline glyphs, the
gradient callbacks are not needed, and the composite
callback only needs to handle simple alpha compositing
(``HB_PAINT_COMPOSITE_MODE_SRC_OVER``).

The paint-image callback is only needed for glyphs
with image blobs in the CBDT, sbix or SVG tables.

The custom-palette-color callback is only necessary if
you want to override colors from the font palette with
custom colors.
