Re: [pygame] Pygame for SDL 2, and how it may look.

Thanks for the link. I had not even thought of OpenGL yet. OpenGL was 
something to be tackled later.

One thing to note though, a programming choice in C may not make sense 
in a higher level language such as Python. C encourages choices based on 
physical data representations. Python types and objects allow for 
abstractions independent of physical representation. So Classes can be 
designed around what you want to do, not what you are actually working 
on. Too me, if there was a strict one-to-one relation between a window 
and a renderer, then why not have an object that can be both a renderer 
and a window.

But yes, if a separate Window and Renderer is more intuitive to most 
people, then that is the way to go. Anyway, the complicated, and unclear 
to me, window/renderer relationship makes a combined object a 
questionable choice.
