Test performance of 565 bitmap scaling
This would catch b/70172912
On Linux desktops, see the difference between 8888 and 565 using:
nanobench --config 8888 -m ^bitmap_RGB_565_scale$ ^bitmap_BGRA_8888_scale$ ^bitmap_RGB_565_scale_bilerp$ ^bitmap_BGRA_8888_scale_bilerp$
On Android, use:
nanobench --config 8888 -m ^bitmap_RGB_565_scale$ ^bitmap_RGBA_8888_scale$ ^bitmap_RGB_565_scale_bilerp$ ^bitmap_RGBA_8888_scale_bilerp$
The results are similar if nanobench is run with --config 565. So
it seems that the destination color type isn't very critical.
