Comment 7 for bug 1580123

As noted in https://bugs.launchpad.net/xorg-server/+bug/883319/comments/62 , the fix for #883319 requires --panning to be specified with --scaling in order to disable the mouse constraints when scaling.

Ideally, xorg should be modified such that the mouse constraints are calculated based on the --scaling and --panning settings, rather than being disabled when --panning is enabled. Short of that, it would be nice if xorg was modified to disable the mouse constraints when --scaling is enabled (in addition to when --panning is enabled). If neither of those can be accomplished, it would probably be sufficient to simply document (in the man page?) that --panning may be needed to disable the mouse constraints when using --scaling.
