DESCRIPTION
Each of the mlib_GraphicsFillCircle_*() functions draws a filled circle
with the center at (x, y) and radius r.
Each of the mlib_GraphicsFillCircle_X_*() functions draws a filled cir‐
cle in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsFillCircle_A_*() functions draws a filled cir‐
cle with antialiasing.
Each of the mlib_GraphicsFillCircle_B_*() functions draws a filled cir‐
cle with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsFillCircle_AB_*() functions draws a filled
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.
