[vtk-developers] No video hardware warning dialog ??

[David Gobbi]

Hi Bill,

If the VFW32.LIB is not present on all win32 systems, then it is best to
to go with option 1 (i.e. set VTK_USE_VIDEO_FOR_WINDOWS to OFF).
Otherwise people might end up distributing binaries that only work on
systems that have VFW32.

I can make the change ASAP.
