From 9ca562765b3b765aeee7eb487eded0093c5be935 Mon Sep 17 00:00:00 2001
From: Chris Want <cwant@ualberta.ca>
Date: Tue, 28 Jan 2003 05:16:41 +0000
Subject: Added x-ray bones support (sgefant ended up doing the bulk of the
 work when he added the button). The new x-ray button is added in the edit
 buttons when the armature is selected. (suggested by ztonzy)
