From 265e0bc43c5f057a28a07c2e38da748971d7a993 Mon Sep 17 00:00:00 2001
From: iovar <iovar@f606c939-3180-4ac9-a4b8-4b8779d57d0a>
Date: Sun, 21 Jan 2007 01:09:32 +0000
Subject: Added support for 16bpp color depth. Currently the
 UPDATE_*_PLANE(S)_* macros are duplicated, so they might need some reworking
 (they are perfectly functional though).
