Bit off-topic, but if you can use them, debug contexts offer much 
better OpenGL error-checking experience. 
https://www.khronos.org/opengl/wiki/Debug_Output . Instead of 
checking glGetError() after each call, you can setup a C callback 
that will trigger whenever an error occurs. It also offers some 
vendor-specific performance warnings.
