Layers / Multiple maps at the same time

[edisno]

I have some "overlay" tile providers which provide more detail for some areas, but return "not found" for tiles which should be rendered from the lower (less detailed) tile provider. Any thoughts about supporting this?

For a long time, I have a plan to simply accept an collection of tiles, instead of just single one. Although it might not exactly be your case, since the goal is to render both layers at once (e.g. a map and a hill shading or something), but it could be a start.
