optimizations for D16 using SSE2
skia_bench -config 565 -match bitmap_8888_scale_filter -forceFilter 1 -repeat
30
The result I got on Android platform was below:
w/o this optimization routine:
D/skia ( 1868): running bench [640 480] bitmap_8888_scale_filter
D/skia ( 1868): 565: cmsecs = 286.50
w/ with optimization:
D/skia ( 1463): running bench [640 480] bitmap_8888_scale_filter
D/skia ( 1463): 565: cmsecs = 186.80
The net gain is 34.80%.
