3416 osd local alpha
3450 Local alpha works differently depending on the colour mode. For 32bpp & 8
3451 bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
3454 fully transparent. There is no local alpha support for 16bit 565.
3456 Global alpha is a 256 step transparency that applies to the entire osd,
3459 It's possible to combine colour key, local alpha & global alpha.
