renderengine: clamp XYZ to [0.0, 1.0] in shaders
texture2D can return strange negative values for some YUV textures.
That should be a driver bug. But with scRGB and floating-point
formats, we cannot be sure that colors will always stay non-negative
after conversion to XYZ. We need to clamp XYZ to [0.0, 1.0] such
that the following color processing behaves as expected.
