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. Bug: 116864006 Test: manual Change-Id: I8f432c63b800edc11ce3d86536192a5547144ca5
