We don't use it much because we prefer opengl, and even opengl is disabled we usually have swscale available.
The code looks fine (similar to the opencl version).
It could just be that because we return RGBX instead of RGB, we end up in a different code path: paint_rgb32 instead of paint_rgb24..

trunk fix in r9983: I'm just not clever enough to figure out how to derive the byte order, so we hardcode it instead (big endian not tested)

Will backport.

This may need further work, as the same swapped colours occur with this fix applied (but with different library versions): #937.
