DESCRIPTION
       Each  of  the mlib_GraphicsFillEllipse_*() functions draws a filled ellipse with the center at (x, y), major semiaxis a, and minor semiaxis
       b. The angle of the major semiaxis is t counterclockwise from the X axis.

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

	     data[x,y] ^= c ^ c2

       Each of the mlib_GraphicsFillEllipse_A_*() functions draws a filled ellipse with antialiasing.

       Each of the mlib_GraphicsFillEllipse_B_*() functions draws a filled ellipse with alpha blending as follows:

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

       Each of the mlib_GraphicsFillEllipse_A_*() functions draws a filled ellipse with antialiasing and alpha blending.

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 center.

       y	 Y coordinate of the center.

       a	 Major semiaxis of the ellipse.

       b	 Minor semiaxis of the ellipse.

       t	 Angle of major semiaxis in radians.

       c	 Color used in the drawing.

       c2	 Alternation color.

       alpha	 Alpha value for blending. 0 <= alpha <= 255.

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