Does mali-T760 support high precison for fragment shader?

But, Is that mandatory in opengles driver? I see a comment in r5p0 driver:  "High precision. Only used if the target supports high precision". That means if GPU doesn't support it, it's meaningless if driver support.

Yes; it is part of the mandatory support required for OpenGL ES 3.0.
