//
|

// Most drawing routines have a version that samples from other canvases, and a

// version that samples from a solid color. None of these routines can use
|

// patterns directly, but it is entirely possible to have a pattern draw to an

// off-screen canvas and then draw a shape based on that canvas. As a little

// bonus, you can save the canvas for later so you don't have to render the

// pattern again when you need to redraw the shape.
