1. Probably a solution to auto-scaling the camera w.r.t. data bounds of WorldObject:

• can set width and height of camera using bbox of WorldObjects
• render axes and ticks etc. in one scene with a camera, and render the data in another scene with a different camera. See scene_overlay example.

2. Should probably just always use the current "big_camera" option as default. near and far planes don't have to be so large.
3. Getting the indices of WorldObjects under an arbitrary shape is not a trivial problem. For now just support a using a "RectangleSelector" that is aligned with the axes and use its bbox to find WorldObjects that are within this bbox and then the indices of that WorldObject within that bbox.
4. pygfx.Image tiling for Heatmap
5. For arbitrary Polygons look into triangulation algorithms, https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.Delaunay.html
