	    mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 c2);

       mlib_status mlib_GraphicsFillRectangle_X_32(mlib_image *buffer,
	    mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c,

	    mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 a);

       mlib_status mlib_GraphicsFillRectangle_B_32(mlib_image *buffer,

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

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

	     data[x,y] ^= c ^ c2

       Each of the mlib_GraphicsFillRectangle_B_*() functions draws a filled 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 rectangle.

       y	 Y coordinate of the upper-left corner of the rectangle.

       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.
