* The graphical user interface (GUI) works by splitting the screen in
* horizontal rows, with row height depending on vertical resolution.
*
* The general screen layout is composed by an upper status bar at the
* top of the screen and a lower status bar at the bottom.
* The central portion of the screen is filled by two big text/number rows
* And a small row.
*
* Below is shown the row height for two common display densities.
