DESCRIPTION
     Each of the mlib_GraphicsDrawRectangle_*() functions draws a
     rectangle with the upper-left corner at (x, y), width w, and
     height h.


     Each of the mlib_GraphicsDrawRectangle_X_*() functions draws
     a rectangle in Xor mode as follows:

           data[x,y] ^= c ^ c2

     Each of the mlib_GraphicsDrawRectangle_B_*() functions draws
     a rectangle with alpha blending as follows:

           data[x,y] = (data[x,y] * (255 - a) + c * a) / 255


PARAMETERS
     Each of the functions takes some of the following arguments:

     buffer    Pointer to the image into which  the  function  is
               drawing.


     x         X coordinate of the upper-left corner of the  rec-
               tangle.


     y         Y coordinate of the upper-left corner of the  rec-
               tangle.


     w         Width of the rectangle.


     h         Height of the rectangle.


     c         Color used in the drawing.


     c2        Alternation color.


     a         Alpha value for blending. 0 < a < 255.


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
