First off, thanks for your code!
I'm very interested in your VBOFont classes, because I want to learn about VBO's and I want to learn about having fonts inside my apps
I decided to do some stresstesting, and I fed a 9K text to your tesselator.
I must admit I'm too lazy to get a profiler going at it
but I peppered your code with a few System.currentTimeMillis()

It takes the tesselateText() method in your class about 3.4 minutes to complete the file
The framerate was still acceptable, though (2800+ CPU, NVidia GF4ti)
I wonder where I could take some shortcuts to speed up the process? setting the "curvePoints" parameter lower than 2 created nonsensical glyphs
And secondly, if I want real, raw performance, should I stay away from truetype fonts, or pre-render them into a bitmap ? I suspect half-life 2 uses them for the console, so it can't be
that slow!
