Xfermode: SSE2 implementation of darken&lighten mode
With SSE2 optimization, performance of the related two benchmarks will
improve about 45% on desktop i7-3770. Here are the data:
before:
Xfermode_Lighten 8888: cmsecs = 33.60 565: cmsecs = 48.84
Xfermode_Darken 8888: cmsecs = 34.16 565: cmsecs = 48.99
after:
Xfermode_Lighten 8888: cmsecs = 18.71 565: cmsecs = 25.41
Xfermode_Darken 8888: cmsecs = 18.39 565: cmsecs = 25.40
