Revert "Use bitmap subset for comparison in texture_domain_effect GMs."

This reverts commit 6377f1c1f9a44d5a6b4a7a53840d82885a8ff2ff.

Reason for revert: doesn't work with ES2 w/out NPOT extension

Original change's description:
> Use bitmap subset for comparison in texture_domain_effect GMs.
> 
> This used to do 2 texel subset draws. The second draw tested a
> non-identity local matrix. Now the first draw exercises local matrix and
> the second draws with a proxy that represents just the bitmap subset to
> give a better basis for comparison.
