There are currently three layouts. The 'presentation layout' is very simple and
20

only supports scrolling on a per page basis. As the name suggests the current
page is displayed in the center and zoomed to fit the window. It is active by
default.

The 'grid layout' is much more advanced and offers continuous (smooth, per
pixel) scrolling, zooming and adjusting the column count. Pages keep their
correct relative size and are shown in a grid.

The 'presenter layout' is for giving a presentation. It opens a second window,
to be viewed on the beamer, and shows the current and next slide in the main
window.

For every file passed on the command line a separate process is spawned.
