From 8850a7e20f77c1bd79863667b2f1c64c2d730f38 Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Wed, 9 Nov 2005 00:56:51 +0000
Subject: Move COPY_FLOAT() macro down into glide driver. Rewrite COPY_4FV()
 macro to not use COPY_FLOAT(), and use integer moves as originally intended.
