[Paraview] release/debug modes in MSVC

[David Cole]

If you want to debug things with the Microsoft compiler on Windows, you have
to build *everything* loaded into the process as a "Debug" configuration. It
is worth the extra time taken to do this. Otherwise, you will simply have
mysteries on your hands and you will spend countless hours pulling your hair
out trying to figure out why something is crashing when there is clearly
nothing wrong with the source code...

Mismatches between Debug and Release are just simply not a good idea with
the Microsoft compiler. (Because the Debug/Release variants of the runtime
libraries have different structures associated with memory allocations and
allocating in one while deallocating in the other frequently leads to
disaster...)

HTH,
David
