       Each of the mlib_GraphicsDrawArc_*() functions draws an arc with the center at (x, y), radius r, start angle t1, and end angle t2.

       Each of the mlib_GraphicsDrawArc_X_*() functions draws an arc in Xor mode as follows:

	   data[x,y] ^= c ^ c2

       Each of the mlib_GraphicsDrawArc_A_*() functions draws an arc with antialiasing.

       Each of the mlib_GraphicsDrawArc_B_*() functions draws an arc with alpha blending as follows:

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

       Each of the mlib_GraphicsDrawArc_AB_*() functions draws an arc with antialiasing and alpha blending.

       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.

       t1	       Start angle of the arc in radians.

       t2	       End angle of the arc in radians.

       c	       Color used in the drawing.

       c2	       Alternation color.

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

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