#GUI.Refresh
##Syntax GUI.Refresh
##Description This routine redraws all the widgets in the currently-selected window. This is used when some form of drawing may have overwritten the widgets in a window.
It is often used when there is some possibility that the widgets may have been drawn over. For example, a program that places buttons on top of a background image should call GUI.Refresh when the image is changed.
##Details GUI.Refresh is used by the GUI Library to redraw all the widgets when the background colour of a window has changed.
##Status Exported qualified.
This means that you can only call the procedures by calling GUI.Refresh, not by calling Refresh.
