Summary0009131: vtkVolumeRayCastMapper renders an image 1 pixel too short
DescriptionvtkVolumeRayCastMapper renders an image 1 pixel too short. This is causing major problems when rendering with vtkRenderLargeImage with magnification > than 1 because there is a gap between patches rendered by vtkRenderLargeImage.

The same problem is present in other software volume mappers such as vtkFixedPointVolumeRaycastMapper.

See attached file vtkVolumeRayCastMapper.cxx_patch.txt for a patch that fixes this issue for vtkVolumeRayCastMapper. A similar fix is probably needed for other mappers such as vtkFixedPointVolumeRaycastMapper.

Do you have a small full code example that illustrates this defect?

The goal is the following: have a small example that fails without the patch.
Add the patch to vtk as well as the example as a regression test and make sure it passes.

I uploaded a small test program (vtkLargeImageRenderTest.cpp and CMakeLists.txt) that renders properly with the patch and not without it. I've also uploaded a pngs that show render window with and without the patch.
