Title: bugfixes for fit-to-content-width zoom mode for documents with pages of ...

...different size

Fixes 2 bugs in fit-to-content-width mode with documents that have pages of different size (e.g. manga with spreads)

1. if height of the page is less than hight of the screen, the page should be centered.

2. when pressing pg_bk, zoom mode should be recalculated.
