- \note Uses a fixed, 256-byte array for holding strings.
- The best way around this would be to use vasprintf(),
- but that is not available on WIN32, I believe.
- Another alternative would be to write our own formatter
- from scratch and emit the characters one at a time to
- the GLUT bitmap single-character drawing routine.
- We could also use vsnprintf(), but I'm not sure if
- that is standard...
