Use the stencil buffer, and normal OpenGL clipping, with OpenGL state
put in.

If all the coordsys stuff were working, we'd just put the two coordsystems
of the end points to it. However, since we want rotations and will do them
in nasty ways, we'll probably just have separate coordsys for the ends
of the connections.

How small do you mean? One of the problems is mipmapping: the characters
get blurred because making a large character and then downsampling
gives a blurry small character.

The solution is given in TODO.
