Francois - your card does not have an OpenGL extension required. My Windows
development machine has the same problem. I think Francois intends to detect
whether the color buffer has all of the extensions it requires, and fall
back to a software method if not.

Note the failed assert you see in the debug version (asserts are compiled
out in release mode). For the charts at least, the software methods are
already present, and can be disabled by setting a flag on the
vtkContextScene.
