This is not correct. The color key is entirely handeled witin the DDX
- or better to say the driver.
The XV extension is instructed to fill a certain drawable with data from
the video source. How this is done depends entirely on the underlaying
HW. Therefore letting the driver fill the visible areas of this drawable
with a color key is perfectly valid.
