Change of algorithms for KisPainter::bitBlt

I was trying to compare two algorithms for KisPainter::bitBlt :
- the older one ( I will call this one OldAlgo)
- a new one using KisIterators ( I will call this one IterratorAlgo)
I tried to compare them using valgrind (valgrind --skin=calltree krita
~/test.kra and I quit immediately). The two algorithms seems to have the same
cost when I look at the global cost of krita. But I get some weird results :
- in the call tree of OldAlgo I don't see any call to KisTileMgr::tile
- in the call tree of IterratorAlgo I don't see any call to
and so on. And I don't understand why.
Does someone know what are the <cycle 1> and <cycle 4> functions ?
