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.
