for the time being we don't use it, and I don't plan on using it. for polygon fills there's an AGG function.<br>from <a href="http://antigrain.com">antigrain.com</a>:<br>In <b>AGG</b> you can get the same
visual result using Scanline Boolean Algebra. It operates with scanline
shapes and in average works 5-10 times faster than GPC<br><br><div><span class="gmail_quote">On 8/4/07, <b class="gmail_sendername">Frank Warmerdam</b> <<a href="mailto:warmerdam@pobox.com">warmerdam@pobox.com</a>> wrote:
