19 * An implementation of the Extended Window Manager Hints specification
20 * http://freedesktop.org/Standards/wm-spec/
21 *
22 * Not Implemented (draft 1.3 - 2004-05-01):
23 *
24 * _NET_DESKTOP_LAYOUT (not useful for us)
25 * _NET_VIRTUAL_ROOTS (not useful at all for us)
26 * _NET_SHOWING_DESKTOP should be implemented
27 * _NET_REQUEST_FRAME_EXTENTS may be implemented
28 *
29 * Some _NET_WINDOW_TYPE are simply ignored:
30 * _NET_WM_WINDOW_TYPE_SPLASH
31 * _NET_WM_WINDOW_TYPE_UTILITIES
32 * _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (deprecated)
33 *
34 * _NET_WM_STATE_DEMANDS_ATTENTION state
35 *
36 * _NET_WM_STRUT_PARTIAL should be implemented
37 *
38 * _NET_WM_USER_TIME can be used to decide if we give the focus to a newly
39 * mapped window
40 *
41 * The kill huge process protocol: _NET_WM_PID and _NET_WM_PING
42 *
43 * _NET_WM_HANDLED_ICONS (what to do? Nothing?)
44 *
45 * "Source indication in requests" is not used but can be useful with some
46 * "ignore styles"
47 *
48 * Problems:
49 * - _NET_WM_WINDOW_TYPE_TOOLBAR is interpreted in a different way
50 * in GNOME (the spec) and in KDE 2/3.0 (~ simple dock?).
51 *
