Why Paginator setItems() simply trim to first chunk?

[alexgheorghiu]

I was reading the code for Paginator's setItems($items) and saw:

    $this->items = $this->items->slice(0, $this->perPage);

and wonder why would you pass whole collection only to trim to first chunk of data?

My feeling is that we should have something like

    $this->items = $this->items->slice( ($this->getCurrentPage()-1) * $this->perPage, $this->perPage);

I means get the chunk that is for current page not for the first one.
