Added text. After poring through the Red Book and researching text display options online, I decided to start out with the easiest solution, which is the included GLUT utility, glutStrokeCharacter.

I moved the main action window to the left of the screen, and created a 2D, orthoganal projection text info strip on the right side. The text characters came out extremely large, so currently I am scaling them to make them fit. Later I'll play with the viewport dimensions to try to minimize the scaling operations.
