Dirk Hohndel 4583cd8e09 Picture handling: cleaning up the mess
We had pointers to data structures on the stack which we frequently
reallocated. These data structure contain basically a filename and an
offset. We then create a hash of the pointers to those datastructures with
the filename being the key. And then we passed those pointers around
through a Qt model(!!!) only in order to then later look up by filename
what the offset might be.

I am at a loss for words for the lunacy behind this design.

How about we just remember the offsets and pass the integers around?
