File 0013-Remove-XAA-support.patch of Package xf86-video-voodoo
From 38537b4dffdcba1dfde99f3e7106a5c23c9859b3 Mon Sep 17 00:00:00 2001
From: Alan Coopersmith <alan.coopersmith@oracle.com>
Date: Wed, 22 May 2024 19:02:40 -0700
Subject: [PATCH 13/15] Remove XAA support
Mostly done via unifdef -UHAVE_XAA_H, followed by minor manual editing
Since recent commits require xserver-1.18.0 or later to build against,
there's no reason leaving behind big chunks of code that can only build
against the XAA support removed in xserver-1.13.0 (released in 2012).
