skia2/tests/BackendAllocationTest.cpp
Mike Klein f7eb0544a8 basic, untested BGR 1010102 and 101010x 
Updated every switch that yelled at me, and added support to dm and fm,
and then founds some more switches that shouldn't have defaults...

The tricky spots outside those were mips and dither,
since they aren't simply exhaustive switches.

_Now_ no diffs between RGB/BGR 1010102 and 101010x.

No GPU support.
