Subject: [PATCH] Route pointer events to deepest child view at click point

In X11, the server delivers events to the deepest child window.
In Wayland, all widgets share one frame_buf. WMHandleEvent now
does hit-testing within the view tree to find the correct child
widget for button press/release/motion events.
