- Now the Preview can show free space around the image (the image's corner will coincide with the center of the preview area) - Editing objects can now be manipulated in this free space - The editing mechanism has been split : it was completely handled in rtengine before, now rtengine still handle the pipette's data provider, but rtgui now handle the objects data provider. - Bugfix: when using coarse rotate in the Editor panel, the Gradient widgets are now correctly displayed
