TOC displays the Synopsis DomTree and reacts on clicks. Viewport changes

moved to #1 in TODO list. Let's hope next items won't start from #2..

(*) - Some parts of this item are already done
In progress on the branch (first item comes first):
-> Abstract contents generation [70% missing TextPage only!]
-> FIX: viewport changes the right way when clicking links and TOC items (also
suggested by Mikolaj Machowski). Create a great viewport definition and merge
it inside the synopsis too. [70% done]
-> memory manager with different profiles (mem/cpu tradeoff: {memory saving, normal, memory aggressive}) [20%]
-> ADD: viewport changes the right way when clicking links (also suggested by Mikolaj Machowski) [65% done]
Things to do in order to merge in HEAD (first item has highest priority):
-> take care of naming on merge, too differences (remove some kpdf_* prefixes
......@@ -31,6 +32,8 @@ More items (first items will enter 'In progress list' first):
-> display current page / total pages (with analog indicator too (progressbar/...))
maybe this can be done on a small widget at the top of the toolbox, displaying
'document' informations (pages, current pg, some metadata, etc..)
-> abstract TextPage generation (the last xpdf dependant class!). then go dancing in the
streets.
-> right click and drag while in 'scroll' mode changes to 'selection' mode and selects
-> add kpdf manual in PDF format loaded on the first startup or on menu->help->manual
this visually explains basic usage, mouse buttons functions & more..
