[vtkusers] Need information about "Invalid pixel format, no opengl support" message.

[Ken Martin]

I believe you gave the specs for your desktop as opposed to the laptop.

That message occurs on windows on the old OpenGL backend (and the OpenGL2
backend for VTK 6.3)  It indicates that VTK tried to setup a device context
for rendering but the device did not support opengl, either because VTK
failed to find a suitable device or because on was provided to VTK that did
not include opengl support.

Thanks
Ken
