According to the documentation I've read, the QCRenderer class doesn't ensure that state in GL_CURRENT_BIT, texture and environment mode, and the matrix mode remain the same after rendering. What is the proper way to save/restore all these variables? Can you just use glPushAttrib() with GL_CURRENT_BIT as the argument and then glPopAttrib()? And what about the environment mode (I'm not exactly clear on what that even is)?

Thanks,
David
