3f04ab4fcd swscale: split hScale() function pointer into h[cy]Scale().
This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

actual scaling or pixel format conversion, and thus a performance
gain.

142e76f105 swscale: fix crash with dithering due incorrect offset calculation.
ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte
aligned and thus at a different offset than intended. Forcing 8-byte
alignment forces equal offset of dither16/32 on x86-32 and x86-64.

commit e1197b9e17

    Use av_get_pix_fmt_name() instead.

The symbol is used by some external libs (hi libx264!), this gives
time to them to use the recently added av_get_pix_fmt_name() rather
than an internal symbol.
