Hi Roman,

first fell free to send me whatever code you want to share.
Bumpmapping is done on a very narrow type of objects : clouds.
Their plib scenegraph is very simple and was easy to substitute with custom
code. My feeling is that VBO fit deeper in the scenegraph rendering code and
affect plib itself. Moreover, the data for clouds changes every frame, so,
in this specific area, I doubt it can help, but can be worth to have for terrain.

I am currently experimenting with ssg to replace the state management system
to have something more flexible in the way openscenegraph do these things.
The first milestone will be to have current plib application work as they do now.
Next, I will add multitexturing.

I am currently finishing the initial coding and I think I will be ready to start 
next week.

Fancy stuff will come later.
