Default Depth peeling, multisample buffer, 177.78

Hello,

The depth peeling algorithm in VTK does not work on an nVidia Quadro FX 3600M (512MB) (driver 177.78) when a multisample buffer is used. It works fine if the framebuffer
is not initialized with a multisample buffer. Same problem with an nVidia GeForce 8800 GTX (768MB) (driver 173.14.12).

It works fine on an nVidia GeForce 6800 256MB (driver 192.12) with or without a multisample buffer.

Note that the algorithm takes care of disabling multisampling rasterization with glDisable(GL_MULTISAMPLE).

A detail bug description is in:

bug_vtk_depth_peeling_quadrofx3600m/bug_description.txt

Uncompress the archive with:

$ tar xjvf bug_vtk_depth_peeling_quadrofx3600m.tar.bz2

Best Regards.
