// .NAME vtkMesaRenderWindow - Mesa rendering window
|
|
// .SECTION Description
|
|
// vtkMesaRenderWindow is a concrete implementation of the abstract class
|
|
// vtkRenderWindow. It uses the mangle openGL namespace mgl, so Mesa render
|
|
// windows can be created in the same program as openGL render windows.
