Some codecs require an RGB input format different from the one we get from the X11 server.
ie: nvjpeg only takes RGB and BGR as input but XShm images are in BGRX format.

The commit above makes a massive difference, for some conversions the performance is doubled!
On my test system, going from ~600 Megapixels/s to 1200!
(for others, Cython would generate awful C code and they have been left as they are)

This helps with #3337
