* src/compositor.c (meta_compositor_process_event): change to
track all children of the root window, not only mapped children;
this keeps us from losing track of the stacking order
* src/display.c (event_callback): don't do any of the compositor
event handling inline, do it all in compositor.c
2003-12-13 Rob Adams <readams@readams.net>
Add increased robustness for dealing with all workspaces windows
and MRU lists.
Also add very preliminary _NET_WM_USER_TIME
support, limited to simply listening for the property and keeping
an internal variable updated, and also treating some input events
as though they were user time updates.
* src/window.c (meta_window_new_with_attrs): set on_all_workspaces
in all cases _before_ adding to the workspaces, so that windows
initially on all workspaces are added correctly to the MRU lists.
Fix for #120907.
(process_property_notify): add net_wm_user_time support.
* src/workspace.c (meta_workspace_add_window): handle sticky
windows so that we add to add mru lists if needed
(meta_workspace_remove_window): handle sticky windows so that they
are removed from all mru lists if needed.

* src/display.c, src/screen.c: create the compositor and feed

instead of meta_window_warp_pointer() crack
* src/effects.c (meta_effects_update_wireframe): draw a kind of
grid for the wireframe, instead of just a rectangle, like twm
* src/screen.c (meta_screen_new): line width of 3 for the XOR gc

everything before we delay

* src/screen.c (meta_screen_new): don't select for button
press/release events, as that keeps other clients from doing so,
and it doesn't seem that metacity has any reason to do it.
Patch from Andreas Volz.
2003-06-10 Rob Adams <robadams@ucla.edu>
Update constraints code to support the new _NET_WM_STRUT_PARTIAL
EWMH draft specification. See #86682. Also, fix a bug involving

screen windows
* src/display.c (meta_display_open): add _NET_WM_STRUT_PARTIAL atom

(meta_workspace_get_work_area_all_xineramas): new xinerama
functions, maintain workspace->work_areas with a different
work area for each xinerama. However for now all the work
areas are the same, because haven't quite figured out how
_NET_WM_STRUT is supposed to work
* src/window.c: adapt to new meta_window_* xinerama APIs
(meta_window_get_work_area_current_xinerama): new xinerama

xinerama functions.
2003-02-14 Arvind Samptur <arvind.samptur@wipro.com>

as being supported.
* src/window.c:
(set_allowed_actions_hint): impl setting
_NET_WM_ALLOWED_ACTIONS.
(recalc_window_features): use it here, but only
if things have changed.

Apply blackc@speakeasy.net patch, bug #83940, to do
mini-workspaces similar to the pager, when switching
spaces.
* src/window.c (update_net_wm_state): actually fill in
wm_state_skip_taskbar, wm_state_skip_pager flags
* src/tabpopup.c: support drawing a mini-workspace similar to the
one the pager draws.
* src/stack.c (meta_stack_list_windows): new function to list
the windows in stacking order
* src/screen.c (meta_screen_ensure_workspace_popup): don't pass in
the ugly default app icon for workspaces
* src/display.c (event_callback): fix from blackc@speakeasy.net
to avoid dereferencing a NULL grab window.
