// .NAME vtkMILVideoSource - Matrox Imaging Library frame grabbers
// .SECTION Description
// vtkMILVideoSource provides an interface to Matrox Meteor, MeteorII
// and Corona video digitizers through the Matrox Imaging Library 
// interface.  In order to use this class, you must link VTK with mil.lib,
// MIL version 5.0 or higher is required.
// .SECTION Caveats
// With some capture cards, if this class is leaked and ReleaseSystemResources 
// is not called, you may have to reboot before you can capture again.
// vtkVideoSource used to keep a global list and delete the video sources
// if your program leaked, due to exit crashes that was removed.
// .SECTION See Also
// vtkWin32VideoSource vtkVideoSource
