WebNewer GPUs can handle setting different parts of gl_FragColor, but older ones can't, which means they need to use a temporary to build the final color and set it with a 3rd move … Webhighp has a floating point magnitude range of 2^-62 to 2^62, and a floating point precision (relative) of 2^-16. Whereas mediump has a floating point magnitude range of 2^-14 to 2^14, and floating point precision (relative) of 2^-10. If I'm understanding this correctly, this should mean that mediump would always be less accurate than highp. Why ...
