/*

   In order to speed up the "logout" screen in rotated modes, we need to intercept
   the Polylines function. Normally, the polylines are drawn and the shadowFB is
   then sending a request of the bounding rectangle of those poylines. This should
   be okay, if it weren't for the fact that the Gnome logout screen is drawing
   polylines in rectangles and this asks for a rotation of the entire rectangle.
   This is very slow.

   To circumvent this slowness, we intercept the ValidatePolylines function and
   override the default "Fallback" Polylines with our own Polylines function. Our
   Polylines function first draws the polylines through the original Fallback
   function and then rotates the lines, line by line. We then set a flag and
   return control to the shadowFB which will try to rotate the bounding rectangle.
   However, the flag has been set and the RefreshArea function does nothing but
   clear the flag so the next Refresh that comes in shoiuld be handled correctly.

   All this code improves the speed quite a bit.
