[wishlist request ggv]: keep page centered

["Riswick, J.G.A. van" <J G A v Riswick tue nl>]

HI

I have a feature request for ggv. When stepping through
pages using the <PageUp> and <PageDown> keys, the new page
is always drawn starting from the top-left corner of the page. 
This is not so convenient when using a large magnification 
such that the margins of the page are not shown. One then has
to recenter each time a new page shows up.
 Maybe it would be more convenient to
have the <PageUp> and <PageDown> keys behave in the same
way as when clicking a page number on the side panel. Or
alternatively, one could implement an option that the pages
always stay centered.

best regards
