Hi all,

Some little things:

* fixed a hang in the cvs version when lots of text gets printed
* fixed a memory leak when loading shaders
* added a shader memory cache - clear with (clear-shader-cache)
* added (print-info) - prints out what's cached (textures, shaders,
meshes) and the scenegraph in text form

Also, some pictures of a recent performance from me! (thanks to Dr Mo)
