Anyway, and that's for sure, the work on zooming is not completed by this MP.

We still have three relevant things to do:

1) Add the double-tap-to-(un)zoom gesture.

2) Properly define the zoom behaviour (minimum zoom, maximum zoom, default value) for the following three form factors:
        - Touch device with screen.width < units.gu(80) - a.k.a. phones
        - Touch device with screen.width > units.gu(80) - a.k.a. tablet
        - Desktop
   We should also take care that the three types of documents we support through LibreOffice (Text, Spreadsheet and Presentation) have some different requirement.
   I started to have a look at this, but it needs to be planned accurately.

   In particular on phones we should limit the minimum zoom to the value set by the "Fit to width" zoom (e.g. Text document).

3) Introduce two new zoom modes: "Fit to Height" and "Automatic".
   "Automatic" mode should be a mix of "Fit to Height" and "Fit to Width". We need it in order to ensure that slides of presentation documents will be always fully visible, no matter which is the size/ratio of the application window.
