Copy created Diagram image to Clipboard

They already copying selected entries from BigTable with Ctrl+C and paste them with Ctrl+V into other application. This doesn't work with Diagrams naturally.

It is not hard to add this feature to Diagrams, but I'm thinking about also including this feature to Dfgrams and Polefigures. However, this would lead to a problem that at up two entities (Dfgram+Diagram, Dfgram+Polefig, Dfgram+Tables) could be at the same time on the Screen which would support this shortcut/feature. This would definitely lead to confusions for the users. I think the best choice would here not just add a Shortcut but to add a button.
