Let me try to explain it with an example

Something like
o layer1
 - shape1
 - shape2
o layer2
 - shape3
 - shape4

which are displayed in the following order

-shape1
-shape3
-shape4
-shape2

is allowed by odf and was possible with koffice apps before. So if we now 
change our painting algorithm to us a hierarchy this is no longer possible. If 
we only change the painting algorithm then the shapes will be displayed in the 
wrong order:

-shape1
-shape2
-shape3
-shape4

and this needs to be avoided as it changes the appearance of document. Instead 
we need some kind of algorithm to e.g. move the shape which is no longer 
possible in one layer to the layer where it can be at the z-index that it 
needs to be. Any ideas what would be a good work around?
