    remote-desktop: Synchronize remote desktop API with API in mutter
    
    This fixes some documentation issues and introduces two new properties
    CapsLockState and NumLockState.
    These two properties will be used in later commits to synchronize the
    lock states in mutter with gnome-remote-desktop.

+       The base for these emulated discrete pointer axis event is the discrete step

+       This means that for a delta dx (or dy) with the value 10.0 one emulated
+       discrete scrolling event is emitted.
+       For a high resolution smooth pointer axis event, a smaller value is submitted
+       for each scrolling step.
+       This means: For a double resolution mouse wheel one emulated discrete event
+       is emitted for 2 smooth pointer axis events with each having the value 5.0.
