bool FV_VisualDragText::reposOffsets	(	UT_sint32	x,
		UT_sint32	y
	)

This method is called at the commencement of a visual drag. If the offsets to the caret are too big, this method will adjust them and shift the image of the dragged text to a comfortable distance fromthe caret. Returns true if the offsets are shifted. UT_sint32 x pos of the caret UT_sint32 y pos of the caret
