9.2.4 Anti-aliasing function
CORAL performs anti-aliasing to make jaggies less noticeable and smooth on line edges. To use this
function at the edges of primitives, redraw the primitive edges with anti-alias lines.
( The edge of line is blended with a frame buffer color at that time. Ideally please draw sequentially from
father object.)
