Outlines are drawn by a two-pass rendering algorithm. In the first pass, the object ID number is written into the alpha plane. The alpha plane is then copied and used as a texture. The second pass determines which part should be outlined from that texture information. The alpha comparison feature assists in this processing. (For details, see <A href="#Algorithm Details">Algorithm Details</A>.)</P> 21<h2>Coverage</h2> 22 23<p>This list doesn't contain settings for drawing other than outlines.</p> 24<TABLE border="1"
