// GL Error checking macro
// this function is useful for tracking down GL errors, which otherwise
// just result in undefined behavior and can be difficult to track down.
// Just call it 'VerifyGLState()' after a sequence of GL calls
// if GL_DEBUGGING and HAS_GL are defined, the function checks
// for GL errors and prints the current state of the various matrices;
// if not it's just an empty inline stub, and thus won't affect performance
// and will be optimized out.
