tickit_pen_ref, tickit_pen_unref - adjust the refcount of a pen

tickit_pen_ref()  increments the stored refcount of the given pen instance by one. It returns the pointer
       argument itself, so it is useful for chaining.

       tickit_pen_unref() decrements the stored refcount of the given pen instance by one. If the refcount drops
       to zero, the instance is destroyed. This will release any resources controlled by it and unbind  all  the
       bound event handlers, causing handlers to be invoked with the TICKIT_EV_DESTROY flag if appropriate.
