[evince] [libview] Split EvPixbufCache into dynamic and static data

[Carlos Garcia Campos <carlosgc src gnome org>]

commit 3a8589a7c5e0394df456074048845cddd04bc43d
Author: Carlos Garcia Campos <carlosgc gnome org>
Date:   Tue Dec 8 18:23:50 2009 +0100

    [libview] Split EvPixbufCache into dynamic and static data
    
    Dynamic page data (page surfaces and selections) that depend on current
    scale/rotation, keep in EvPixbufCache with the current cache approach.
    Static page data (links, annots, images, text and forms) that don't
    depend on current scale/rotation, have been moved to EvPageCache and they
    are never removed from the cache.
    Fixes bgo#602405.
