This is required to customize it via stylesheet.

Katarakt now exposes a dbus-API that allows TeX-editors to synchronize
the positions in source code and pdf via synctex.

TODO: The API allows to specify positions in the PDF as (page,x,y)
triple, but the x,y coordinates are currently ignored or set to 0,
respectively. We need more katarakt-internal API for this to be
implementable.

Single, double and triple right click start the selection. The selected
text is copied to the X11 selection buffer.

Refactored mouse click handling for this feature.

With this option and background_color_fullscreen you can freely configure the color of your liking.

Default key binding: F9

Every time a jump occurs its origin is saved. You can then move through
those saved positions, e.g. to return to the table of contents after
having read a section.

This feature is not yet finished, essential features like opening a
second window are not done.

Layouts don't get destroyed on layout change anymore. Instead, a
cur_layout pointer is set. Common attributes are copied over, the rest
is persistent (e.g. zoom, offset, ...).

Configure via background_opacity setting. Always draws fully opaque when
in fullscreen.

This is useful when editing TeX documents. If there is an error
somewhere and only a part of the file was generated the position will be
the same after having fixed the problem.

Uses to the old search for poppler versions that don't support it yet.

The command line options right before each file will be used
individually.

If there were no hits and you tried to cycle through them the program
crashed.

auto_* removed, every action now has a fallback for layouts that don't
support smooth scrolling.
Half and full screen scrolling added.

I use QSettings in ini format. See the qt documentation to learn about
file locations. If there is no config found the default values are used.

Also, fixed memory leaks.

Currently supported options are:
	- page NUM
	- fullscreen
	- help

Press u/i to rotate counter-/clockwise.
Search rects and clickable links are not yet rotated correctly.

If scroll_{page,smooth} did not move the view, don't redraw

Also, remove one old TODO line

Do not update if a page that is currently not visible finishes
rendering
