When a drop is performed on a text editor, the target is a StyledText.
The behaviour of the drop could depend on the editor which contains the
StyledText. For example, the drop on a JavaEditor would be performed in
a different manner from the drop on a CDT editor.
By the content, I could have an algorithm to try to find the appropriate
editor, but I think there should be an easier way.
I have looked at ProjectionDocument and related classes, but nothin
strikes me as evident.
