Summary:
This way pages that take more than 500ms to render get updated every so often so that the
user can see that the program didn't hang, it's just that it's taking long to render

How does it work:
* What it does is really closing and opening the file again through poppler
* This means that things that are generated in "open" time like Page, Rects, Annotations, Forms need to be updated
* For Page what we do is swap the PagePrivate so that other classes that hold Page* don't break
* Since some parts of the PagePrivate can be reused, we move them in PagePrivate::adoptGeneratedContents
* For all the commands in the undo stack we need to update the annotations/forms it refers to, added a new function to do that
* The annotationmodel needs updating it's pointers
* The widgets for the forms are reused and their form* updated
* the widgets for the videos are recreased since videos don't really hold much content (you lose the playing status on save but i think that's acceptable)
TODO: Make this work for .okular files
TODO: For files with password we will need to reload the file, asking for the password again and thus losing the undo stack, warn the user
TODO: autotests
This way dvi and any other potential user gets it for free
The diff is huge, but the synctex files are just moves.
And the code in core/ is also mostly just a move from the generator_pdf.cpp code

Diggory i think there was a misunderstanding in our discussion
The patch is unfinished (not goot to commit with a TODO)
and needs to be improved (need to find a way to not break ABI, QSize param should be const &) please
open a reviewrequest and we can discuss/finalize it there.

The text generator is the only one compiled now.
This version links for me but then doesn't find its KPart on startup.
TTS has been completely disabled as well as some other things like the
about dialog.
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

Unfortunately as we can't add new strings to stable versions it'd say "unwnown error" if that happens
Don't think it's too bad since this shouldn't be happening much

Just use the pointer as id :-)
This is BIC and SIC, increase the soversion now to makes sure we don't forget in the future

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.
and implement it in the pdf generator, others welcome to implement the function
for other generators
