In Sirius #359, a bug has been discovered in GMF. In the method org.eclipse.gmf.runtime.diagram.ui.tools.DragEditPartsTrackerEx.snapPoint(ChangeBoundsRequest) the x and y coordinates are used. But if the moveDelta is a PrecisionPoint, preciseX() and preciseY() should be used instead. Indeed, according to the zoom level, preciseX or preciseY can be something like 0.5 and must no be considered as 0.
