Subject: Sort shader program input attributes by name
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=0d94309bc07629feea62bd03837b6e21ccc15b6f;p=libs%2Fgl.git

The lookup requires this.  It seems to have gotten broken in 2576b61, but
since the only user is InstanceArray, it wasn't noticed until now.
