Almost all of the pieces are together for the MVP. Letter color is now selectable and ignores dark mode, pen size has two options, the gesture system has been completely redone (as a single UIRepresentable that handles both rotate and move). Major next step is a moveable canvas, and an eraser.
The eraser is the challenging one, as I’m rendering pixel data from a PKDrawing, and so the eraser has to manipulate pixels (luckily already separate from the background).
