From 85655f6c409cfbadbf96b652af1dca571ef9d9bf Mon Sep 17 00:00:00 2001
From: iovar <iovar@f606c939-3180-4ac9-a4b8-4b8779d57d0a>
Date: Sun, 8 Jul 2007 15:21:11 +0000
Subject: rmdmacro.h: made appropriate changes to rgb2yuv macros, so that cache
 blocks will calculated during the conversion and not later, on a step of
 their own. Added MARK_BACK_BUFFER* macros, so that cursor will be updated
 normally during conversion.
