It was a simple bug in the XY Cut layout recognition code that made it too eager to see columns everywhere.
Also removed the dependence of the layout analysis algorithms on the display DPI (introduced by the recently added feature of using KScreen) to make their behavior more predictable and reproducible.

Includes some fixes from Albert:
* kscreen cmake fixes
Don't make libkscreen mandatory, give the proper version we need
* Fix the @since
* Kill Resolution and use a QSizeF
I first thought QSizeF didn't make sense, but well what's a dpi if not a number of pixels in width and some others in height?
* Remove unwanted const
* Remove unneeded utils.h includes
* Fix comments on realDPIXY()
* Make it compile in non X11

therefore removes the extra method and updates the comment reference in the

It's useless as it will be reset anyway on the close down procedure
and it will cause a crash if you are unlucky.
Reason:
* In the document observers qset pageview comes before
* We are closing and notifySetup with an empty vector
* pageview empties its vector in notifySetip
* part sees the notifySetup and resets the search
* resetting the search calls another notifySetup with the non empty page vector
that will be deleted asap when we go back to the first notifySetup
There are another billion ways to fix this:
* Don't allow nested notifySetup
* Clear the running searches before sending the first notifySetup
* Empty the pagesVector before sending the first notifySetup
* etc
But i feel this is the less invasive one (even if it may not be the most technically correct)

This patch introduces viewport transitions for undo/redo actions on annotations and forms. When an annotation/form action is undone/redone but the associated annotation/form is not currently visible, the viewport is updated to center on the undo/redo action. If the annotation/form is visible, the viewport is not updated.
The viewport transitions for the Find action have also been updated to this same algorithm. Previously the viewport was moved to center on each matching search term even if the search term was already visible in the viewport. This lead to unnecessary viewport transitions if the search term matched several items in a single paragraph for example.
These proposed changes to the viewport transition behavior are consistent with the find and undo behavior of many existing applications including Kate, Open Office, and Foxit PDF Reader.
This makes automagically work the printing on printers with
hard-margins since the QPrinter dialog margins are initialized to the printer
hard-margins. If you still want the old and mostly unuseful
behaviour of not having any margin (and thus your printer not printing things on the borders) you
can always set the margins to 0 in the dialog

Also simplified code a bit by removing unnecessary calls to toLower in TextPagePrivate::findTextInternalForward and TextPagePrivate::findTextInternalBackward I also fixed a small bug: the letter capital I with dot above (U+0130) did not match itself in case-insensitive mode on Qt 4.8.4 (U+0130 still does not match lowercase i (U+0069), which can be considered another bug, that I didn't fix (although this behavior conforms to the Unicode case folding rules)).
(I did not implement the Knuth-Morris-Pratt algorithm that I promised in a comment of Bug 323263 because on second thought I find that the win, if any, would probably be negligible except for some very special documents and special query strings.)

Prefer the backends that declare explicit support for a mime over the ones that get the support by inheritance
In the fictionbook case it was happening that application/x-fictionbook+xml inherits text plain
so when we ask for the fictionbook backend, we get both
the one that says
MimeType=application/x-fictionbook+xml;
and the one that says
MimeType=text/plain;
and then it happens that the second has bigger X-KDE-Priority
By prefering the ones that explicitely declare support for a mime we "fix" this
OTOH we may want to explore showing the backend selector if there's more than one by default

The patch de-singletons the PageController class.
The PageController is now per-document and it gets deleted when the
document is closed.
As consequence of this, the RotationJob's done signal will not be
delivered if the document has been closed, and thus this fixes the
crash.

Sometimes annotations created on tiles mode were not shown immediately.
What requestPixmaps do is given a PixmapRequest, change its
normalizedRect attribute so the rect is tile aligned. However
refreshPixmaps was creating a PixmapRequest with the rect already tile
aligned and then delivering the PixmapRequest to requestPixmaps, which
would trye to take the requested rectangle and change it so it is also
tile aligned. Since the PixmapRequest delivered by refreshPixmaps was
already aligned, the requested rectangle was inflated by the tile
alignment procedure. After that the generated request becomes bigger
than the defined threshold and is discarded. This patch actually
removes the tile alignment logic from refreshPixmaps and let only the
requestPixmaps handle this.
It is still not perfect because for some reason poppler is painting outside the boundaries box (or we are not creating/setting it correctly)
but at least now it's not ultra hard to click in a note application at high zoom

It was only used to return 1, that was then used in
CHMGenerator::textPage, that code still looks a bit fishy, but that was already there, it's just now that looks a bit more fishier
1) Fixed underflow when memoryDiff > memoryToFree
2) Use current viewport's page number instead of any visible page as
page from which distances are calculated
3) Renamed currentVieport to visibleRect, because the currentVieport is
a different thing
The new class TileNode represents a node in the tree structure
whereas Tile is just a data structure to store the pixmap and tile rect
and is used outside tiles manager.
The miss counter was taken away. Now the algorithm relies on the
distance between the tiles and the viewport.
Also the visibleRect() and setVisibleRect() methods were removed from
TilesManager since we now pass this information to
TilesManager::cleanupPixmapMemory()
When searching backwards end is not actually words.end but words.begin (since the loop goes backwards) hence we can't pass end to stringLengthAdaptedWithHyphen
I've now renamed end to loop_end to make it a bit more clear.

Some requests may take a while to process in a highly zoomed region.
Since those requests are not yet finished, other requests to the same
region are likely to be made (specially if the user is scrolling fast)
and the generator will have to render the same region repeatedly.
Also when changing zoom rapidly some pixmaps can arrive at the tiles
manager when another request has already been posted. This pixmap is not
necessary anymore and should be discarded (the tiles manager will get a
new pixmap anyway).
This fixes the auto-start feature of PDFs generated with the LaTeX movie
package, which uses the additional action of a widget annotation to start
the movie when entering the page.

The visible region was set in the PixmapRequest only a tiles manager was
available. Because of that the generator could check if it was supposed
to used tiles by simply checking if its normalized rect was null.
However is good to know the visible region even when a tiles manager is
not present. This way if the request is big enough to start a tiles
manager we already know the visible region and can change the
PixmapRequest accordingly.

The splitting was only executed after the pixmap arrived the tiles

Fixes a bug that causes the extraction of a wrong bounding box:
If the request queue is not empty, signalPixmapRequestDone causes a new
pixmap request to be started, thus overwriting mPixmapGenerationThread's
mCalcBoundingBox before it is read by the if in the next line.
Now signalPixmapRequestDone is called after the bounding box is saved,
so that new requests are started only after all data from
mPixmapGenerationThread have been saved.

Previously it was cleaned in FIFO order
I also moved the pixmap selection logic in a separate function, that

Note: This behaviour is yet not optimal for the thumbnails panel,

It actually serves three purposes:
a) Make sure all the values are there (this should be always true, but doesn't hurt making sure) because if SwapFree was there but SwapTotal was not, it'd be a mess
b) add up things in order so we don't underflow, currently the code did process stuff as it came in the file, and it happens that SwapTotal appears before SwapFree in /proc/meminfo so it actually did "MemFree:" + "Buffers:" + "Cached:" - "SwapTotal:" + "SwapFree:", which can underflow if "MemFree:" + "Buffers:" + "Cached:" < "SwapTotal:"
c) Do not underflow at all, so if "MemFree:" + "Buffers:" + "Cached:" + "SwapFree:" < "SwapTotal:" we return 0 correctly not a zillion of free memory

BUGS: 291129
The only affected generator is poppler (because it's the only one with
saving support).
Since version 0.20, Poppler can save annotations to PDF. If the user is
using an older version, this patch warns him that annotations are not
saved.
This patch makes sure that the file saved in the .okular file keeps
the original filename (and, in particular, the extension) even if the
user is re-exporting a .okular archive as .okular archive. Before this
patch, the file boundled in the .okular archive would be named like the
.okular file it was exported from (eg foo.okular instead of foo.pdf).
Note: Okular had no problems in reopening it, but advanced users
unpacking the ZIP file obtained a .okular file which is actually a
native file, and not an okular archive.
1) If the user had previously annotated the document with an old okular
version and the document contains existing annotations and no /Encrypt
(ie the case where annotation changes are no longer saved locally), make
Document::saveDocumentInfo write the original unmodified local
annotations back to XML, so that it seems that the original file was not
changed. If the user makes annotation changes, code from previous
patches already asks him to save them to a different document on close.
2) Ask "Save changes?" if the user has modified annotations in a .okular
archive.
BUG: 300197
3) Turned a "sorry" message in a "information" (with dontshowthisagain),
because now we also have the "Save changes?" prompt to inform the user.
4) Suppressed all annotation-related message boxes on document opening
- Make "Comment" the default stamp instead of "Note" (because we used to omit
the "icon" in the exported DOM if it was "Comment")
- Don't omit the icon name anymore
This patch turns Okular into a ReadWritePart. Annotation editing is always
disabled if we're loaded as ReadOnlyPart, no matter the document type.
REVIEW: 105020
The only affected generator is poppler. Note that:
Document has /Encrypt <=iff=> SaveInterface supportsOption(SaveChanges) is false
This patch enforces the following behavior (and warns the user the first time
he edits an annotation).
- If the document has /Encrypt, warn that "Save as" is not available, but it's
possible to export as okular archive. New annotations will be automatically
saved to XML as usual.
Note that the previous patch already made all existing annotations uneditable,
because there's no way to save them.
- If the document has no /Encrypt and there are existing external annotations,
warn that changes won't be saved automatically. The user needs to "Save as" or
changes will be lost.
- If the document has no /Encrypt and there aren't existing external
annotations, don't show any warning. New annotations will be automatically saved
to XML as usual and to file if "Save as" is pressed.
The previous counter-based approach didn't take into account existing names used
by external annotations and names used in other pages.
Instead of creating a document-global table of used names, I used random UUIDs
as a source of unique names.
Modification and removal of *external* annotations are disabled by this
patch. Note that this change doesn't remove any functionality, because they
have never been implemented (AnnotationProxy is defined by the previous
patch).
The #if0'd blocks will be enabled by a future patch that provides fallback
behavior for generators that don't support saving changes.
mTextPageReady is only used for threaded generation and this is a sync one so resetting it to true make very bad things happen
An improvement of this area is needed since it makes no sense canGenerateTextPage returns mTextPageReady when generateTextPage doesn't use itB

Sorry i failed to fulfill my promise
This is needed because sometimes the hash had collissions and make it impossible to know which character we had to put back
Now we just keep the word and the characters together in the same class and it is much easier to correlate them
Also the code gets much more simplified and less new/delete are needed
This fixes the crash in 287138
I am still concerted that we use the page width and height in TextPagePrivate::correctTextOrder, but that should not cause crashes, at most some misplacements of very small text
TextPagePrivate::correctTextOrder was running makeAndSortLines + calculateStatisticalInformation to calculate the tcx, tcy
to pass it to XYCutForBoundingBoxes and then in XYCutForBoundingBoxes we were doing the same but just for when countLoop was not 0, thus
if we remove the first code and remove the check for countLoop being not 0 we end up with the same behaviour
