88e4163970 Use the extension version of FBO extension instead of core. 
This will allow solvespace to run on pre-OpenGL 3.0 implementations,
such as VirtualBox (and possibly others).

However, VirtualBox's handling of framebuffer objects is buggy;
it tries to draw over our X window and fails to do either.

I hate OpenGL.

e27c6b56c3 Implement offscreen rendering using GL framebuffer objects. 
Apparently pbuffers are also a deprecated and unportable
way of offscreen rendering. They're not supported by
Chromium OpenGL implementation, which is what 3D-accelerated
VirtualBox uses.

This would also help a future OS X port.
