[vtkusers] Depth peeling

[Francois Bertel]

Hi Paul,

I never received the email you're talking about...

What graphics card to you have?

Can you send me the output of the LoadOpenGLExtension and TestOpacity tests, please?

First, make sure your VTKData directory is up-to-date.

>From the root of your build directory of VTK type this and send me output1.txt and output2.txt:
$ ctest -R LoadOpenGLExtension -V > output1.txt

$ ctest -R TestOpacity -V > output2.txt

1. The first test will give me accurate informations about your graphics card/OpenGL driver and supported OpenGL extensions
2. The second test will tell me if depth peeling is actually used, and if used if it failed.
