yes, containments can be different sizes. that also doesnt matter.

containments can be associated with a given screen and a given virtual 
desktop.

a view can be associated with a containment.

the best solution (without lots of explanations, sorry) will be to simply make 
all DesktopViews have the same zoom level; zooming out in one should zoom out 
in all, zooming in on one shoudl zoom in on all. picking an activity when 
zoomed out should only interact with the View that the event came from.

so we probably want to put the actual zoom in/out control in PlasmaApp, which 
owns the DesktopViews and have it set all the zoom levels globally.
