// .NAME vtkOpenGLImageMapper - 2D image display support for OpenGL
// .SECTION Description
// vtkOpenGLImageMapper is a concrete subclass of vtkImageMapper that
// renders images under OpenGL
// .SECTION Caveats
// vtkOpenGLImageMapper does not support vtkBitArray, you have to convert the array first
// to vtkUnsignedCharArray (for example)
//
// .SECTION See Also
// vtkImageMapper
