The generic format must be choosen dynamically dependent on the graphics
hardware. Otherwise it could be redundant: 
Let's say I choose 32bpp as generic format, but I'm running a machine with
8bpp colors. 
That would mean: 
sample an 4bpp bitmap up to 32bpp (the generic format) then fed the
drawing routine with this 32bpp bitmap, which down-samples the bitmap to
native 8bpp. 

This could also be done this way: 
sample 4bpp up to 8bpp, fed the bitmap drawing function with that 8bpp
bitmap.
To me this sounds like one sampling process less. :)
