Stop referencing gl_FragCoord z and w components.
This fixes an Adreno driver bug where GL programs fail to link if the FS refers to these components of gl_FragCoord.

Simple GPU based dithering:
If dithering is turned on, apply an effect that filters the pixel through
the following pipeline:
for each channel c:
1. Compute quantized colors [low, high] that c is between
2. Pick high by flipping a coin weighted by (c - low)
