Description
ImageJ 1.* does not have a selection tool: when the user hovers drags a handle, the corresponding selection is modified, when the user clicks & drags somewhere else in the selection, the whole selection is moved.
Add a DelegationTool that uses JHotDraw to detect when the mouse cursor is hovering above a selection or selection handle and transparently hands off to the SelectionTool in that case; otherwise, a new selection is added or replaces the complete selection, depending whether the Shift key is pressed (add) or not (replace).
There is a third mode in ImageJ 1.*, unfortunately: holding down the Alt key when selecting something removes that part from the existing selection. The problem is that this can modify the type of the selection: a rectangle from which a part is been removed is very unlikely to be a rectangle still. See #878 for details.

The first part of this is now committed.
The Alt key handling needs #878 to be addressed first, though.

- Status changed from accepted to closed
- Resolution set to fixed
- Blocking 878 added
Selection tool is successfully eliminated. Alt key will not work until subtracting ROIs works (see ticket #878). But there is nothing left to do for this specific ticket.
