Johan Malm c1472cb64b Support window-rules
Two types of window rules are supported, actions and properties. They are
defined as shown below.

    <windowRules>

      <!-- Action -->
      <windowRule identifier="some-application">
        <action name="Maximize"/>
      </windowRule>

      <!-- Property -->
      <windowRule identifier="foo*" serverDecoration="yes|no"/>

    </windowRules>

Rules are applied if windows match the criteria defined by the
'identifier' attribute which relates to app_id for native Wayland windows
and WM_CLASS for XWayland clients.

Matching against patterns with '*' (wildcard) and '?' (joker) is
supported.

Add 'serverDecoration' property.

* that occur after the mouse button is released, as the client
* catches up with pending configure requests. So as a fallback,
* we resort to a geometry-based heuristic -- also not 100%
* reliable on its own. The combination of the two methods
