pyglet/matplotlib integration experiments

Hi all,

I've been playing with pyglet and matplotlib integration using the Agg
backend as suggested some time ago on this list. The idea is to let
matplotlib do all the pretty stuff and let pyglet do the rendering of
images (currently, only imshow has been proxied).

Image rendering is done through GL texture using shaders for both
nearest/bilinear and bicubic filters and color LUT. Currently, this
allows to use matplotlib colormap with under/over colors but no bad
color yet.

Just run 'demo-matplotlib.py' and 'demo-matplotib-2.py' (implementation
of the dynamic_image.py animation demo).
