AW: Using VerySleepy shows that SdrGrafPrimitive2D::SdrGrafPrimitive2D uses
nearly 100% of the time by calling the GraphicObject constructor. This call
registers the object at the graphic manager, adds it to sume buffering and uses
ImpGraphic::ImplGetChecksum when doing this.
This is surprising since it's a copy constructor which may simply copy the
checksum, knowing that the object gets copied, not a new one created.
If this cannot be changed it will still be possible to use only one instance of
the GraphicObject, e.g. using a shared ptr.
Setting KA on copy.
AW->KA: Why is copy-constructing a GraphicObject thus expensive? Does it have to
re-calculate the involved checksums in a copy constructor...?
