[vtk-developers] GUISupport in vtkRendering

[tom fogal]

We were investigating switching to the Qt stuff in GUISupport/ instead
of some no-longer-maintained code that we hack every now and again to
keep working.

However it seems when one enables this, Qt gets linked into
libvtkRendering.so.  We have some programs that do rendering without a
GUI, and we are not willing to link in Qt or even have it as a build
dependency for that part of our software.

Any thoughts on a `libvtkGUI.so' or similar library?
