[vtk-developers] Mouse wheel support in VTK

[Mathieu Malaterre]

Commit has been done. There is still work to be done in class that 
bridge to VTK, for example the borland one, the wxWindows, the Qt, the 
GTK (in c++ and in python).

I'll try to fix them ASAP.

For the borland one, there is a TCustomControl::OnMouseWheelUp event, 
maybe it can be use ?
