/**
* @class vtkCocoaTkUtilities
* @brief Internal Tk Routines for Cocoa
*
*
* vtkCocoaTkUtilities provide access to the Tk internals for Cocoa
* implementations of Tk. These internals must be implemented in a .mm
* file, since Cocoa is Objective-C, but the header file itself is
* pure C++ so that it can be included by other VTK classes.
*
* @sa
* vtkCocoaGLView
*
* @warning
* This header must be in C++ only because it is included by .cxx files.
* That means no Objective-C may be used. That's why some instance variables
* are void* instead of what they really should be.
