    -- 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.
