Currently, the position information available to guide the paste action in placing graphical representations includes whatever arrives from the clipboard and whatever is selected in the current diagram. This enables use cases like pasting at the same location as the copy, at an offset from the copy, at the location of the selection, at an offset from the selection, or replacement of the selection. 

I propose another use case: pasting at or at an offset from the location at the mouse pointer when the user issues the paste command. This is useful whether the paste operation occurs in the same diagram as the copy or a different diagram. It prevents the user from having to drag the pasted result an arbitrary distance across the diagram.

One way to achieve this is to add methods to IPasteContext that supply the target diagram, and the X and Y location of the mouse within that diagram. The paste() method could then optionally use this information to place its graphical representations.

Supplying the target diagram may be generally useful beyond this specific use case since acquiring it from the objects supplied by the getPictogramElements() method is something that every paste() method has to do and it is possible that it would be easier for the framework to do than for the client.

Reproducible: Always
