There's a "SharedPointer" flag you can add to the device section in  
the configuration file which causes a device to share the pointer  
with the virtual core pointer. So all devices with the SharedPointer  
flag set will use the same cursor sprite.
It worked for mice, but I haven't tested it for a while and it could  
be broken since I removed the virtual core pointer from the device list.

Eventually I'll add an additional argument to specify which device to  
share the sprite with but that's rather low on my todo list right now.
