Summary:                    BUG: vtkFixedPointVolumeRayCastMapper in MFC
Application, non standard std::bad_alloc behavior
Description: 
vtkFixedPointVolumeRayCastMapper causes MFC application to crash on 32-bit
systems, during rendering of big volumes. The problem is the non standard
hahavior of the new operator. MFC provides its own operator new, which throws,
instead of std::bad_alloc, a CMemoryException* on allocation failure. This is
also the case in vtkFixedPointVolumeRayCastMapper during allocation of
ContiguousGradientNormal and ContiguousGradientMagnitude in the
ComputeGradients() function.  

To work around this issue we can either use "catch(...)" instead of
"catch(std::bad_alloc &)" or use the "new (std::nothrow)"!

This behavior was verified under VS9 and VS10!
