ImageManager

ImageManager does three things:

Tracks requests for icon images from tile workers and sends responses when the requests are fulfilled.
Builds a texture atlas for pattern images.
Rerenders renderable images once per frame

These are disparate responsibilities and should eventually be handled by different classes. When we implement data-driven support for *-pattern, we'll likely use per-bucket pattern atlases, and that would be a good time to refactor this.
