Fuzz runtime effects more quickly by painting less.

The fuzzer hit a 20-second timeout by crafting a very complex shader
(it calls normalize thousands of times) and then painting it to our
128x128 test surface.

For the purposes of a fuzz test, we don't need to paint so many
pixels. We now use a 4x4 surface; it'll still catch bugs, and will
execute 1024x faster.
