better mapping of cocoa concepts to vtk concepts
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Assuming VTK uses the same concept as X11 and Win32 in their api (which is very likely), I suggest mapping these concepts for Cocoa...
NSView -- VTK WindowId n/a -- VTK DisplayId NSWindow -- new VTK concept, or keep it in Cocoa/Carbon implementations. Its possible for the code to get an NSWindow from an NSView, so one shouldn't be required to provide that info to vtkCocoaRenderWindow.
