This patch modifies the skeleton plugin and some core stuff to make the screen scrollable via middle mouse drag, but it's just to test the propagation of SDL::Event to the plugins.
It works but I don't know if it is the proper way to propagate the events.
I would really appreciate it if you reviewed that propagation code as I still learning C/CPP and there might be some problems.
