MRG - MeRGed from head
(*) - Some parts of this item are already done
In progress on the branch (first item comes first):
-> FIX: rework PageView (QScrollView) to gain speed and reduce memory consumption
-> ADD: reading aids (accessibility) [settings config done while now]
-> ADD: click over image allows "save image" (and display rect around image too) [50% done]
-> ADD: viewport changes the right way when clicking links [30% done]
Things to do in order to merge in HEAD (first item has highest priority):
-> memory manager with different profiles (mem/cpu tradeoff: {memory saving, normal, memory aggressive})
-> rework QScrollView internals to NOT generate paint events on invisible widgets.
the current behavior, using a large scrollview and the clipper is *Very* bad, wasting repaints
everywhere, even in widgets that get hidden. Need to solve this on its roots, a paintEvent patch

-> minimize PageView's reLayout and requestPixmaps on changes
-> this may be postponed after merge: implementing async document generator using Albert's generator thread
-> pageview: fix keys/mouse navigation in both single/continous modes [60% done]
