aligning_guidelines:
- Bugfix for rotated objects - rotated objects should be aligned correctly
centering_guidelines:
- Fix for objects with different origin (originX or originY != 'center')
- Fix for clear lines
Fix if objects have different origins (originX != 'center' and/or originY != 'center')
Lines now removed correctly on object:moving (bug since commit c4bec7045532886a338ef7ae91c80bfd8fb28851)
[BACK_INCOMPAT] for fabric.js versions < 1.0.0
"object:moved" --> "object:moving" (since it's a continuously fired event).
"object:scaled" is gone (since this case can be solved with "object:modified").
"group:modified" is gone (since this case can be solved with "object:modified").
"group:selected" --> "selection:created".
"before:group:destroyed" --> "before:selection:cleared" (only fires when there is active object or group).
"after:group:destroyed" --> "selection:cleared" (only fires when there is active object or group).
