Another point to make is that if you need deprecated functions, DerelictGL3 is not what you want. You should import derelict.opengl3.gl and use DerelictGL.load/reload instead. It includes all of the deprecated functions. Just make sure you have created a context that allows you to access the deprecated stuff. As far as I know, 4.0+ (perhaps even 3.3) are core only. Note that you *do not* need to load both DerelictGL3 and DerelictGL, as the latter handles everything for you.
Which I see you are already doing! I should have looked at your code first.
