From a12cc580ce0b2be91dd4e567e28b72a11975f537 Mon Sep 17 00:00:00 2001 From: "Andrew C. Oliver" Date: Thu, 25 Jul 2002 05:10:23 +0000 Subject: [PATCH] Added preliminary support for Palletes. Still need to write add/remove/change functions. Added this so that if someone else wants to finish it before I get to it, they can. (have at it!)
