Title: Apply the current zoom level value to each page in Presentation Mode

This patch makes sure that each page fits properly in Presentation Mode, even for documents with different sized pages.

Fixes #3827 and probably [bug 804074](https://bugzilla.mozilla.org/show_bug.cgi?id=804074) (*the testcase is no longer available, but it sounds like the same issue*).
