[Debian-med-packaging] Bug#1013154: vtk-dicom: vtk[6,7] removal

[Mathieu Malaterre]

Hi David !

We are trying to transition from vtk6/7 to vtk9.

Would it be possible for you to release a newer vtk-dicom release with
the latest changes to deal with VTK9.

Otherwise I'll try to cherry-pick some of them (eg.
8d51cb0410a1f77dabcc566836f93463eb775244 and
d15c9b9100ff1df6caca8cc1073b121cb234396c seems important)

Thanks much !
