oBrush           Brush Object to fill its whole area
 --------------------------------------------------------------------------------

   The oBrush of a Window Object or a descendant class Object, has a
   brush Object which is automatically built based on the Back color
   of the Object, unless the user specifies a special Brush Object when
   calling the constructor:

   Example:

   DEFINE WINDOW oWnd FROM 1, 1 TO 20, 40 ;
      TITLE "Hello World" ;
      COLOR "GR+/R"

   ACTIVATE WINDOW oWnd

   This Window has Yellow color (GR+) as nClrFore DATA and Red color (R)
   as its nClrPane DATA. It also has an oBrush Object built using the
   Red Color.


   Example:

   DEFINE BRUSH oBrush RESOURCE "FillOne"

   DEFINE WINDOW oWnd FROM 1, 1 TO 20, 40 ;
      TITLE "Hello World" ;
      COLOR "GR+/R" ;
      BRUSH oBrush

   ACTIVATE WINDOW oWnd

   This Window has Yellow color (GR+) as nClrFore DATA and Red color (R)
   as its nClrPane DATA. It also has an oBrush Object, but the Brush was
   already built.

   This means the full color of the Window will be done based on the
   Brush Object, but if we use the :Say( <nRow>, <nCol>, <cText> ) method
   of the Window, the text will appear by default as Yellow on Red.
