Using PIPE_SWIZZLE insteads sounds reasonable.
Not sure though how I feel about using X/Y/Z/W instead of
RED/GREEN/BLUE/ALPHA. I think there's situations wher using r/g/b/a is
nicer compared to x/y/z/w. (If these were just defines could of course
have definitions for both versions but with a named enum it's probably
not a good idea two have two named enum...)
