Hi everybody, This is a proof of concept for oversampling to decrease artifacts in rendering overlaps. The attached images show how the artifact visible at the top of B, E, F, T decreases as we increase oversampling from 1x1, to 2x2, to 4x4. The price is doubling and quadrupling the rendering time. The proposal is to have it available as FT_RENDER_MODE_SLOW specifically for fonts that need it.
I am seeking feedback if 2x2 is good enough, or 4x4 is necessary. I will also reply with a set of patches to try it and comment on it. Regards, Alexei
