[vtkusers] OS X Python Carbon Valid Pixel Format??

[Yves Starreveld]

Hi, Karl,

VTK is currently hard coded to request a hardware accelerated context.

The code requesting the context should be modified to request one, but 
still continue if it doesn't get one.

Have a look at the vtkOpenGLRenderWindow Cocoa and Carbon specific 
files for more info.
