+####WGExit
+Cleans up and shuts down WeeGUI. If you want your application to return cleanly to Applesoft when its down, you must call this. Otherwise you may get ProDOS complaining it is out of buffers, or other strange behaviour.

 To Do:
 ------
 
-- Repainting a view while the mouse cursor is on it will cause artifacts when mouse moves
-- Quitting sometimes leaves BASIC in inverted text mode
-- Quitting with button highlighted leaves us in inverted text mode
-- After initial run of basic demo, additional run fails with no buffers available
 - Make WGFillRect support 1 height and 1 width
 - If called in inverse mode, clear screen clears inverse
 - Fix unclosed PRE tags in documentation
