Detailed Description

Contains all the style information for the formela.

The idea is to change the values here (user configurable) and have the elements paint themselves with this information.

All distances are stored in point. Most methods return pixel values.

Sets the zoom by hand.

This is to be used in paintContent.

Returns
whether there was any change.

Change the zoom factor to z (e.g.

150 for 150%) and/or change the resolution, given in DPI. This is done on startup, when zooming, and when printing. The same call combines both so that all the updating done behind the scenes is done only once, even if both zoom and DPI must be changed.
