Higher quality but 4x slower than vanilla. Click and drag to draw. Hit space to render, z to show/hide brush controls, and x to show/hide quality controls. WARNING: changing resolution will clear the canvas. After using a slider, you might need to click somewhere else for scratch to resume registering your inputs. Features: volumetrics, 3x angular scaling, dda, soft shadows, tinted 'glass', relatively scene independent performance (more occluders = higher performance as rays stop earlier)
