Formerly we'd zero the image data and then pull out a plane at a time.
It's faster to apply the planemask after the fact, since that turns the
GetImage into a memcpy:
100000.0 101000.0 (1.010) (copy 0xaaaaaaaa) ShmGetImage 10x10 square
42400.0 59400.0 (1.401) (copy 0xaaaaaaaa) ShmGetImage 100x100 square
3040.0 5280.0 (1.737) (copy 0xaaaaaaaa) ShmGetImage 500x500 square
96100.0 95200.0 (0.991) (0xaaaaaaaa) GetImage 10x10 square
29600.0 36800.0 (1.243) (0xaaaaaaaa) GetImage 100x100 square
1850.0 2620.0 (1.416) (0xaaaaaaaa) GetImage 500x500 square
Measured with Xvfb at depth 24 on Skylake i7-6560U.
