[vtkusers] vtkOpenGLGPUVolumeRayCastMapper on a specific GPU

[Lars Friedrich Lars]

Thank you very much for the info! I was not aware of the NVIDIA-specific wgl-command. As VTK's GPU-ray-caster currently supports NVIDIA only, it seems to be perfectly suited for the planned purpose (on windows). I will try to implement the proposed ideas within the next weeks, and will keep the user list or VTK wiki update-to-date concerning this issue.
Thank you again!
