-// Wayland event information is being passed in as arguments to the callbacks.
-// (See wayland_input_device.{h,cc} for information on the callbacks and how
-// events are processed.)
-// In order to provide a more generic look for events we wrap these arguments
-// in specific event structs. Then define a WaylandEvent as a union of all
-// types of events that Wayland will send.
-//
-// The following fields are common for most event types and their use is
-// similar:
-// - time:
-//    The time of the event. This should be monotonically increasing.
-// - state:
-//    The value of the button event as given by evdev. This is 0 if button
-//    isn't pressed.
-// - modifiers:
-//    Stores all the keyboard modifiers (Ctrl, Alt, Shift, ...) currently
-//    active. The modifiers are values as defined by xkbcommon.
