Events that the windowing system sends to Servo.



Sent when no message has arrived, but the event loop was kicked for some reason (perhaps by another Servo subsystem).

FIXME(pcwalton): This is kind of ugly and may not work well with multiprocess Servo. It’s possible that this should be something like CompositorMessageWindowEvent(compositor_thread::Msg) instead.


Sent when part of the window is marked dirty and needs to be redrawn. Before sending this message, the window must make the same GL context as in PrepareRenderingEvent current.


Sent when the window is resized.


Sent when a navigation request from script is allowed/refused.
