Replace Copyright text by a more discrete watermark.
CamiTK interactive viewers
Since the update to support VTK 7, the copyright text disappeared from the right corner of the Interactive Viewer instances.
Although the copyright text was a bit 1980's it was nice to have something that was a bit like a watermark. It was quite intrusive though (but it was possible to remove it by Right-Clicking on an interactive viewer). The best would be to replace it by a more discrete watermark.
I suggest using a smallish CamiTK logo with some transparency in the very bottom very right corner of the viewer.
The advantage will be to encourage people to leave the logo (it is too small to be annoying in most of the case), and therefore be able to promote nice projects that use CamiTK.
→ May be have a little dialog to promote citing the article as well/instead of the logo, when the user decide to disable the logo?
