A large number of changes to the size of panels to enable "Laptop Mode" where all of the panels and controls are scaled down so that they fit on screen and are still in correct proportion. For the laptop I'm using for testing, the resolution is 1920x1080. For this, a scaling of 0.7 seems to work. The on/off of the "laptop Mode" is controlled by a checkbox in the preference panel (under the General tab).

There are still more panels to update in the next commit.
