Summary0008782: Add multisampling to win32 and cocoa render windows
DescriptionRight now only X and carbon render windows take the MultiSamples ivar into account. Win32 and Cocoa don't, probably for historical reasons.

Win32 and Cocoa should be fixed.

We are now using VTK in our own Win32-based project for the purposes of data visualization. To make it more eye-candy we tried turning on the multisampling in "vtkWin32OpenGLRenderWindow", but it didn't work due to the obvious reasons described above.

Thus I implemented a multisampling technique in a class I called "vtkWin32OpenGLRenderWindowMultisampled" by making it a direct descendant of "vtkWin32OpenGLRenderWindow" and modifying a couple of inherited methods there.

The technique itself is loosely based on a tutorial from NeHe Productions ( http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=46 [^] ) and uses some Win32-specific GDI calls and some other OpenGL-related stuff found on the Internet.

The solution in general tends to be "quick and dirty", but has been positively tested on a set of machines with different video hardware under different Windows versions (including WinXP 32-bit, WinXP 64-bit, Win7 64-bit).

I hope the code will help to implement this nice feature and make VTK better and more popular in Windows environment. Believe me, hardware-accelerated multisampling is a thing!
