    Message : Clarify aliasing rules in CHROMIUM_bind_uniform_location The CHROMIUM_bind_uniform_location spec previously had some conflicting information on when uniform location aliasing was allowed. Now the section on uniform location aliasing makes it clear that aliasing locations of two statically used uniforms is an error. This guarantees compatibility between different compiler versions that may treat a different subset of uniforms as active, depending on optimizations. It follows the spirit of GLSL ES 3.00.6 spec section 12.46, that has similar rules for attributes. The implementation is fixed to correctly follow the spec. When flattening uniforms, static use is tracked separately from activeness.
