+// 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.
