--- Comment #12 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
Don't turn my comment wrong, it will most likely use *more* CPU. Quick
profiling show that memory operation (load/store) are part of the bottleneck.
You need 3 store operations per pixels in RGB, and only 1 for RGBx. For that,
you need to be aware the RGBx buffers are aligned, you you can address as an
array of uint32. This is not the case for RGB, so you can only grab uint8.
I don't have any use for that element myself, that just how Open Source works.
People bring their use cases, add code to fulfill it. Maintainers review, and
when happy merge and maintain. Doing the later maintenance of your code and use
case isn't a small thing.
