The internalFormat comes from our use of glTexImage*D, so the OpenGL
docs for glTexImage2D are very useful:

No mention of GL_RGB32F in the above docs though.... but this is
rather a late addition to the family, so you'd probably have to look
at OpenGL extension registry or OpenGL 2.x/3.0 docs for an answer.
