After calling this function, colors will be filled with the palette
colors. If colors is NULL, the function will just return the number
of total colors without storing any actual colors; this can be used
for allocating a buffer of suitable size before calling
harfbuzz.global.otColorPaletteGetColors a second time.
The RGBA values in the palette are unpremultiplied. See the
OpenType spec CPAL
section for details.
