I'll add a 64 bit version, plus some other changes:
- simply the reduce-to-memset code
- use full range for alpha even for yuv (apparently that's how it works)
- allow passing 0 width/height, in which case the function is a NOP,
but the error return will indicate whether the pixfmt is supported
- change EINVAL to ENOSYS for unsupported pixfmt cases
