Sk4px: Difference and Exclusion
This will cause minor (off-by-one) diffs due to a little lost precision:
colortype_xfermodes
mixed_xfermodes
xfermodes2
xfermodeimagefilter
xfermodes3
xfermodes
Desktop:
Xfermode_Difference_aa 9.77ms -> 7.32ms 0.75x
Xfermode_Exclusion_aa 8.49ms -> 6.21ms 0.73x
Xfermode_Difference 17ms -> 7.54ms 0.44x
Xfermode_Exclusion 13.5ms -> 5.09ms 0.38x
N7:
Xfermode_Difference_aa 32.2ms -> 27.6ms 0.86x
Xfermode_Difference 43.9ms -> 32ms 0.73x
Xfermode_Exclusion_aa 40.5ms -> 26.7ms 0.66x
Xfermode_Exclusion 71.5ms -> 23.9ms 0.33x
This wraps up the xfermodes implemented in Sk4f.
