Refactor image handling

[Tamas Zolnai]

Hi there,

Just a short note about that currently I'm working on refactoring of image handling (Graphic / GraphicObject).
Mainly working on swapping mechanisms which cause a lot's of headache as I see. LO's bad swapping
mechanism leads both to image loss and to ineffective behavior. So it's time to clean this up a bit.

Any idea, advice is appreciated.


Best Regards,
