Just making KisTileDataWrapper no longer a shared pointer gave me some speed
already in the current trunk version of the tiles impl, so, yes that's a good
thing to do. Qt doesn't have pooling functionality (there's QThreadPool, but
that's a different thing), you might want to use QThreadStorage to put your pool
in, but you'll probably have to either get an existing implementation from
somewhere or write your own.
