…dering This uniform was already defined for other uses previously. `textureSize()` is known to be slow on mobile platforms due to how the drivers implement it there, so it's best avoided.

Looks great! Its nice that the albedo texture size is already available.
For posterity, the problem with textureSize() isn't a driver issue. On all platforms textureSize() does a full texture read which is much more expensive than just reading from a uniform.
