Frankly making (almost) all 16 bit d3d formats always use 24 or 32 bit
GL formats is not what I would suggest at start if realized that at
once. But if to go that way the first version of my patches are still
valid suggestion. Maybe patches 3, 4 can be dropped as that was added
for completeness, I am not aware of the real applications depending on that.
