This is a quick stress test I made with squares made of individual pen pixels. Pen could potentially be used for pixelated sprites to save assets. Mode 0 is pen. This is less stressful and allows for easy changes of saturation, but it is drawn as individual circles (unless the size is less than 3, in which it draws squares). Mode 1 is stamp. This is more stressful and doesn't allow for easy changing of saturation, but it renders each pixel as a square. Mode 2 is a slightly different version of Mode 0, where the pixel moves into the next pixel and then updates. This fills the gaps but doesn't allow for transparency, and is also slightly more stressful than Mode 0.
