Related: tdf#152703 Eliminate potential blocking during live resize
Some events and timers call Application::Reschedule() or
Application::Yield() so don't block and wait for events when a
window is in live resize.
Also, only native events and timers need to be dispatched to redraw
the window so skip dispatching user events when a window is in
live resize.
Lastly, only higher priority tasks need to be fired to redraw the
window so skip firing potentially long-running tasks, such as the
Writer idle layout timer, when a window is in live resize.
