Hmmm...what about presenting the option of 64-bit floats? I'm probably
exposing my ignorance of some cairo internals that wouldn't transition
to floating point very easily.
If that were possible (and desirable), we might be able to cover all
cases well with just two options: 32-bit 24.8 fixed point and 64-bit
floating point. The devices on which the fixed point option would make
sense probably wouldn't care about the limited coordinate space.
