[vtkusers] vtkActor2D to vtkImageData* Possible ?

[Glen Lehmann]

Hi Glenn and Toon,

A while back, I updated John Shalf's vtkOpenGLOffscreenRenderWindow for 
VTK > 4.3  and the X11 environment, as the last time I checked it was 
written for vtk3.2.

It can be found here:

http://www.imaging.robarts.ca/~glehmann/OffScreen/OffScreen.html

Recently, others have reported that it still works fine, including Mac 
OS X via X11.

Cheers,
Glen
