- 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
- Removed the "Rendering intent" setting from Preferences,
- Hard-code "relative colorimetric" intent everywhere,
- Filter through output profile before filtering through monitor
profile if using a monitor profile,
- If not using a monitor profile, a direct sRGB conversion is done,
