Do our own fp16 conversion in ResampleEffect.

This not only fixes issues with poor downconversion on ATI, but also
allows us to normalize while being aware of fp16 roundoff issues.
Seems to about cut the error in half in the HeavyResampleGetsSumRight
test, which as far as I can see would take us up to 10-bit accuracy.
