cc: Stretch textures by .5 texels to prevent out of bounds sampling
This will allow us to revert texture clamping logic that reduces
the fill rate on some devices.
Instead of requiring us to clamp texture sampling, this patch
stretches textures by .5 texels past quad bounds to avoid
blending in invalid texels when GL_LINEAR filtering is used.
