DESCRIPTION
       Each of the mlib_GraphicsDrawCircle_*() functions draws a circle with the center at (x, y) and radius r.

       Each of the mlib_GraphicsDrawCircle_X_*() functions draws a circle in Xor mode as follows:

	     data[x,y] ^= c ^ c2

       Each of the mlib_GraphicsDrawCircle_A_*() functions draws a circle with antialiasing.

       Each of the mlib_GraphicsDrawCircle_B_*() functions draws a circle with alpha blending as follows:

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

       Each of the mlib_GraphicsDrawCircle_AB_*() functions draws a circle 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.

       r	 Radius of the arc.

       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.
