I am completely new to opengl, pyglet and miru... you have been
warned :) It is quite ugly, but is throw away... I am in it for the
learning.
The following code shows my attempt to muck around with primitives and
textures. I am not sure how given an image loaded as below, I can
actually get it to display.
Any help is appreciated:
