The last two days I've spent trying to get font rendering to work. I chose FreeType.
It is almost satisfactory. There's an issue with the transparent pixels. They are always black.
I've also done some cleaning up in the code in general.

Ooh! Looks fun! Good luck to Programming OpenGL. It for certain is a challenge!
Be sure to turn on alpha blending. there are also some other things that can cause transparent pixels to ignore the alpha channel. Be sure you aren't rendering directly on to the backbuffer, because it doesn't understand alpha and this can cause blend issues. You might want to render a black rect on the background first to try and fix that.
somehow I get the feeling we're going to be seeing lots of screenshots with hamsters duplicated across the screen repeatedly
Best of luck! Hope you have a more positive experience than I did with opengl and c++. Graphics is fun though.
I managed to fix it. I was using GL_RGBA as the format when creating the texture. I tried using GL_ALPHA instead, and now it looks much better. I guess it makes sense for it to work, as the texture itself only needs to be white, while the color comes in as I draw the quad.
