Avoid deep copies of pixmaps when using cache in QGraphicsView.
When we have already a pixmap of an item in the cache, we should
remove the entry from the cache otherwise when we will repaint/modify
the copy of the pixmap (the copy of the cache) then we will trigger a
deep copy ; this is because both entries in the cache and our copy
share the same data and if you modify one of them a copy is triggered.
I have added a benchmark as well to test that.
