turtle

The turtle package provides a friendly and software-rendered drawing solution, for simple programs and games that happen to be written on a Friday.

Features

turtle basically gives you 5 ways to draw on screen and express yourselves.

• A fast but limited software rasterizer with the canvas() API call. (See project: dg2d)
• A slow but nicer software rasterizer with the canvasity() API call. (See project: canvasity)
• A text-mode console with the console() API call. (See project: text-mode)
• An immediate software-based UI with the ui() API call. (See project: microui)
• Direct pixel access with the framebuffer() API call.

The draw order is as follow:

• Direct pixel access, and canvases, can happen simulaneously in the draw override.
• Text console is above that, but also happen in the draw override.
• Immediate UI is on top, and happen in the gui() override.
