This broke some conversions (screws up chroma), for example:
 yuv420p 96x96 -> argb  64x 64 flags= 2 CRC=9cc86f93 SSD=    2,  957,  666,    0

It can be tested using that swscale-test2 tool I sent with:
swscale-test2 -i ~/input.bmp -sws_flags 2 -pix_fmt yuv420p -s 96x96
-scale -store -s 64x64 -pix_fmt abgr -scale -s 96x96 -pix_fmt yuv420p
-scale -ssd
