/**
 * To better group the options together and allow the window to be scalable with additional OpenRCT2 options, the window has
 * been changed to a tab interface similar to the options window seen in Locomotion.
 *
 * TODO Some parts, particularly the string handling and order of widgets needs reorganising.
 *      Padding between the widgets and the window needs reducing, an artifact from originally being inside group boxes.
