renderengine: avoid divide-by-zero in shaders We have max(1e-6, color.y) to make sure the divisor is non-zero. But when mediump means half-precision floats, 1e-6 is smaller than the minimum positive normal number. The line might have no effect at all. This is noticed when looking into the referenced bug.
