Is there some simple way to achieve hard-edged rendering for the Ink tool? I find the hard edged rendering used in INDEXED mode best for drawing lineart, but dislike the other constraints (no drawing modes/opacity/layer modes) imposed by working in INDEXED mode. So far, I've tried to find the part of the code that handles indexed images without success, and enabled the Hard edge toggle for the Ink tool (which does nothing in this case, as I suspected -- it only applies to brush-based paint tools).
Is this code shared between tools? (for instance, the Airbrush behaves similarly in INDEXED mode)
Where would be a good place for me to look in order to implement this?
