[vtkusers] missing include for vtkMILVideoSource.cxx?

[Shi Sherebrin]

In version 1.21.6.1 of vtkMILVideoSource.cxx (VTK source CVS download 
2003/06/12, using ) I got the following compilation error which kills 
the build:

C:\Tools\VTK\Hybrid\vtkMILVideoSource.cxx(571) : error C2061: syntax 
error : identifier 'vtkDataArray'

Is the correct way to fix this to include "vtkDataArray.h" in the same file?

thanks,
Shi.
