Are you sure this patch does what you need ? It just shortcuts the minimal 
computation of the container bounds for pools and lanes. What happens for 
subprocesses ? What happens if you place the task out of the pool bounds ?

Sorry for the late reply.
Yeah it does, the elements are displaced because the event 
"layout.bpmn2_0.pool" is triggered before the elements are placed correctly 
within a pool.

As you can notice if you read the code on 
/editor/scripts/Plugins/bpmn2.0/bpmn2.0.js the method handleLayoutPool assumes 
that all elements are correctly placed and really fits within the pool as it 
is. The problem is that when the diagram is loaded all its elements are created 
on point(0,0), it means that the pool need to be resized prior to this event 
and that what this code does.

Notice also that the _oldBounds need to be set to the current value because the 
old value was referencing the (0,0) point, which is the origin of all the 
displacement.
