  * There are three large Mesa data types/classes which are meant to be
  * used by device drivers:
  * - struct gl_context: this contains the Mesa rendering state
- * - struct gl_config:  this describes the color buffer (RGB vs. ci), whether or not
- *   there's a depth buffer, stencil buffer, etc.
- * - struct gl_framebuffer:  contains pointers to the depth buffer, stencil buffer,
- *   accum buffer and alpha buffers.
