Rework colorfilter bench

Browse Source 
Previous structure didn't measure anything but new/free cost. All of the
constructs turned into (eventually) drawRect + color.

New version also measures that, but in a clearer way, so we can examine
all the variants, and assume that they should all be about the same.
