Last week we moved the geometry for UberSDF to being quads. Since SDF rendering is behind a flag we didn't get automatic performance benchmarks on that change. We need to run new gallery against special mesh vs quad for desktop and mobile platforms manually.

The concern is alpha overdraw and the extra fragment shader overhead when using quads versus fitted meshes.

Doing spot tests on Wonderous and our //dev/benchmarks/macrobenchmarks would be worth looking at as well.
