[vtkusers] Depth Peeling VTK5.2 ATI Cars

[Iñigo Barandiaran]

Hi

I'm working on a medical application,and i'm using VTK as a 
Visualization API.We want to render some translucent objects and we are 
trying to use Depth Peeling technique that is integrated in 5.2 version.
The problem is that we can not use that technique in ATI's card. I saw 
in the vtk code that the problem is already detected. I have also tried 
to solve the problem modifying the vtkOpenglRenderer. I think the 
problem is in the shader in shadow2DRect. I've tried to use other 
approaches such as texture2DRect or texture2D with no success.
Do you know if it is possible to solve this problem?.

Thanks in advance!
