Issue #2033 - Temporary fix of R<->B channel swap.
We have a BGR/RGB channel ordering mismatch here. to at least
provide proper display, a quick&dirty byte swap on the output
buffer will fix this for now, but we should look into seeing where
the surface mismatch is caused.
std::swap() should optimize pretty well in any of the used
compilers, but if necessary, a full buffer ASM routine can be
slotted in (although on current hardware I doubt this will be
even noticeable as it is)
