X.Org bug 4947/Sun bug 6646626: Xv extension not byte-swapping properly
Fixes ArcticaProject/nx-libs#165 commit dfd682b582636a36345144bcf835e3ee46718d90 Author: Alan Coopersmith <alan.coopersmith@sun.com> Date: Wed Jan 2 19:27:22 2008 -0800 X.Org bug 4947/Sun bug 6646626: Xv extension not byte-swapping properly X.Org Bugzilla #4947 <https://bugs.freedesktop.org/show_bug.cgi?id=4947> Sun bug 6646626 <http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6646626> Don't use swapped data after swapping it. When done swapping data, send the swapped data, not the address of the pointer to it, to the client.
