Which describes exactly what many common graphics operations are:
color space matching, color format transformations (ie, ARGB to
BGRA), "blitting", etc.
That's what I tried to point out - many apps does such like things,
but the coder needs to arrange his code the correct way or the optimizer
needs to recognize and probably rearrange the binary.
Could you outline, in which 'non simple cases' (reads: e.g. single
bitblt call)
RB manages to figure out AltiVec optimizable code? Does RB perform
strong/aggressive
rearrangements of code? When does it fail to rearrange code?
