  Seems reasonable, but maybe that should be the minimum, as opposed to the 
rule.  That way we don't have large dead spots around large objects.

  Of course.

   Right, it should fall onto the top object it's geometric centre intersects.

   I think we can get pseudo-guarantees of this via property ordering, but if 
not, then we need to implement a "int getSequenceFor(propertyName)"

   Right, we need a focusProperty() also then.

   Seems rather straightforward, but we need to be careful not to special-case 
too much.  Everything in view objects need to be very generic so they're 
useful from the scripting side and so we can finish implementing all the 
dynamic loading and creation.  Once the factories are in place, we will be 
able to dynamically load view objects by name without anything new in the 
loader code, and even have view object plugins.
