Detailed Description

A list of shapes that rasterizes once.

The Canvas surface this library exists to provide, without a Canvas. Shapes accumulate with a transform stack and nothing is drawn until tiny_display_render, which is what lets two eliminations run first: a shape outside the target is dropped, and a shape an opaque later one covers entirely is dropped as well. Both are decided from the geometry, so neither costs a pass over pixels.

Larger than a TinyPlan; keep one wherever the caller keeps its image rather than deep in a recursion.
