- * Class: CFont
- ********************************************************************************
- * This is just a quick and dirty class for using wglUseFontBitmaps. I don't like
- * using it because it's slow, but for now that's all I have to use for fonts.
- * It would be nice to test drawing to a normal Windows bitmap using GDI commands,
- * then blitting the text to OpenGL somehow.
