By manipulation the used font pointSize property, we can dynamically scale fonts and derived UI objects. At the same time, we have some logic to determine the default font, its size, etc, for example depending on screen properties. The scaling of the UI (and its font) does not need to interfere with those defaults. However, when we want to reset the pointSize, we alter the default, so a backup of the default is needed. Ok, not al full backup, as the only thing we like to manipulate is the pointSize, to which we want to be able to return. All this leads to this commit. A basePointSize property is added, that is initialized from the default. Due to the binding logic of the QML engine, it is not a classic initialization, but a binding between the 2 properties. We need to break that binding explicitly, so that the original PointSize is always preserved. In addition, a display of the new font property is added to the developers theme test.
