librocket GUI support

Morgul and I started playing with a basic wrapper in Cython earlier today, and between some code from librocket’s pyinvaders sample, a bit of code from GrizzLyCRO’s p3d_rocket project, and Morgul’s pure Python CEGUI bindings (see the Snippets forum) we managed to get this far in one day:

The display works with the full animated panda scene in the background, and it stays correctly sized when resizing the window.

Our code can be found at: bitbucket.org/skewedaspect/pyrokit

Right now, librocket seems to have some issues loading the fonts, but other than that the display is mostly functional. However, there is no keyboard or mouse input yet - that will most likely be coming in the next few days, along with a lot of code cleanup.
