+<var>Run</var> is the method called to start execution of the application. It 
+reimplements the method introduced in TCustomApplication to provide support 
+for the MainForm and processing loop used in a GUI application. The Run 
+method is generally called, via the Application singleton, from the .lpr 
+project file.

+<p>
+If the MainForm property has been assigned, and should be displayed, the 
+AppSetupMainForm method in the widgetset class is called to set the window 
+state for the main form. The Show method in MainForm is also called to scale 
+the form (when needed) to the PixelsPerInch for the monitor. The form is made 
+visible and brought to the top of the Z-Order in the application.
