* Do not allow render targets not explicitly written by the fragment shader to be modified * Shader cache version bump * Remove blank lines * Avoid redundant color mask updates * HostShaderCacheEntry can be null * Avoid more redundant glColorMask calls * nit: Mask -> Masks * Fix currentComponentMask * More efficient way to update _currentComponentMasks
