[Clam-devel] Copy & Paste processings on canvas patch

[Natanael Olaiz]

A revised NetworkCanvas version. I added some selection graphics related 
protected methods-helpers on NetworkCanvas, and used it for a better 
offset point calculation: when you copy/cut a group of processings, 
takes the most left upper point as origin. So, when you paste that 
corner will be under the cursor point (or origin on keyboard action 
shortcut).


Regards,
Natanael.
