keyboard-shortcuts-inhibit: Add client example
Again, copy'n'search'n'replace the idle inhibit example to become a simple keyboard shortcuts inhibit example, adding the active and inactive events. Getting the initial inhibitor needs to be done later than for idle inhibit to avoid an error "xdg_surface has never been configured". Signed-off-by: Michael Weiser <michael.weiser@gmx.de>

/**
|

* Usage: keyboard-shortcuts-inhibit
|
||||
* Creates a xdg-toplevel using the keyboard-shortcuts-inhibit protocol.
|
||||
* It will be solid green, when it has an keyboard shortcuts inhibitor, and
|
||||
* solid yellow if it does not.
|
||||
* Left click with a pointer will toggle this state. (Touch is not supported
|
||||
* for now).
|
||||
* The compositor (de-)activating the inhibitor will also toggle state.
|
||||
* With a compositor supporting the protocol, compositor shortcuts will be
|
||||
* suspended while the inhibitor is active and the window has focus.
