To use this, first compile and get mpx working
Apply patch for gtk-window-decorator, and compile.
Compile resize2 plugin
Plugin another mouse, create 2 new masters, reattach the two mice to control the 2 new masters (at the moment, you cannot use master device 0)
Enable resize2 plugin, disable resize plugin (and probably move as well, as I broke that)
Restart compiz and gtk-window-decorator (important, as they do not autoupdate the devices yet)
Resize a window

TODO:
Modify rest of compiz to take into consideration multiple pointers (I think this should also fix the virtual core pointer problem)
Auto-update device lists (although this should be handled inside compiz, not a plugin)
Optimize
Add some more error checking (mainly for failure to grab and freeing stuff if it fails)
Add move plugin functionality
More things I can't think of right now...
