// .NAME vtkOutputWindow - base class for writing debug output to a console
// .SECTION Description
// This class is used to encapsulate all text output, so that it will work
// with operating systems that have a stdout and stderr, and ones that
// do not. (i.e windows does not). Sub-classes can be provided which can
// redirect the output to a window.

// counting will work. The single instance will be unreferenced when
// the program exits.

// Description:
// Display the text. Four virtual methods exist, depending on the type of
// message to display. This allows redirection or reformatting of the
// messages. The default implementation uses DisplayText for all.
