e.g. level = 0 is translated to GL_POINTS. This doesn't make sense.

I have a few questions:

  1. What should it be translated to?
  2. Why is it translating to GL_POINTS?
  3. Which function is responsible for the conversion?

  1. In this particular case, it should just be a literal 0 and shouldn't be replaced by a GL_ constant.
  2. I assume there's a bug in our code for processing the GL registry that makes us thing the level argument has a type it doesn't actually have.
