Previously, we had ShellAppInfo, which contains fundamental
information about an application, and methods on ShellAppMonitor
to retrieve "live" information like the window list.
AppIcon ended up being used as the "App" class which was painful
for various reasons; among them that we need to handle window
list changes, and some consumers weren't ready for that.
Clean things up a bit by introducing a new ShellApp class in C,
which currently wraps a ShellAppInfo.
AppIcon then is more like the display actor for a ShellApp. Notably,
the ".windows" property moves out of it. The altTab code which
won't handle dynamic changes instead is changed to maintain a
cached version.
ShellAppMonitor gains some more methods related to ShellApp now.
In the future, we might consider changing ShellApp to be a GInterface,
which could be implemented by ShellDesktopFileApp, ShellWindowApp.
Then we could axe ShellAppInfo from the "public" API and it would
return to being an internal loss mitigation layer for GMenu.

We have compatibility code which detects from the window title what
an application is. However, the code didn't handle the case where
we discovered by title, but didn't have the expected .desktop file
installed.
The windows we considered for both the app monitor and the overview
workspaces were the same, but the code was duplicated once in C, once
in Javascript.
For Firefox/OpenOffice, right now we have a workaround in the
code where we look at their "title" property. However, we
weren't monitoring that property for changes, and I'm fairly
certain Firefox at least was mapping a window and then very
quickly changing its title after. So we need to handle
dynamic changes.
Split out the wm_class mapping from the title hack. It was
messy and weird to have the two mixed because they're not
at all related, and we're not trying to handle WM_CLASS changes
right now.
Explicitly connect to notify::title in the case where we had
a title fallback. When a title changes, just treat it as
an add+remove.
In the Application Menu area in the panel, hook up to app-added
and app-removed so we get notification of the active app changing.
Separate the application monitor logic for "tracking" and "usage tracking".
The first means we associate an application with a window. The second
means we count focus time inside that window, and consider the window
interesting from a user point of view.
(Really, should probably split ShellAppMonitor into two classes along
this line, with the second consuming the first).
For the purposes of counting running applications and returning
the list of open windows for an application, skip not-usage-tracked
windows.
Together this allows us to associate the Nautilus desktop window
with the nautilus.desktop, but not show "File Manager" open all
of the time.
Use MetaGroup for a window when looking up applications. If
we know the application for a TYPE_NORMAL window in the group,
use that.
However, we aren't always going to know the application for a window. In
that case, create a fake one.
ShellAppInfo has a "transient" flag so we know not to write these
fake apps to the usage file.
Clean up the idle focus handler to better handle the case where
no window is focused, and where we don't want to track the
particular window.
Update track_window to create the fake window.
When a window goes away, we want to delete the usage.
Rewrite shell_app_monitor_get_running_apps to be based
on the window_to_app hash, because that's what has the pointer
to ShellAppInfo*. Before we were looking up all ids through
ShellAppSystem, but that shouldn't be holding a ref to transients.
Change the well display icon to be centered, since our icons for
window apps aren't 48 pixels.
This is a start at the "Active Appliction Item" component of the
shell design. Currently we just show the currently focused
application. When launching a new application, we show that as well.
The implementation here is not complete; basically when launching
we de-focus the active one, and the application well shows the
most recent startup sequence.
This kind of fails in the case of multiple sequences, and we
also don't correctly de-focus the current window in other
launch paths.
For both of these, because of optimizations a few patches ago, we
ended up relying on hash table ordering which caused instability
in the application well among other things. Define an ordering
for both.
The favorites is just the order of the GConf keys, and new items
get appended. In the future we should allow insertion at any
point which the grid could use.
For running applications order, define a new "initially_seen_sequence"
transient variable which is just an monotonically incrementing
integer assigned to an application for the first time we saw it
running in this session. When an application is closed, it's reset.
The previous application monitoring code was originally designed
to be based on WM_CLASS, which was then resolved on a server.
We have that resolution code locally now, so instead
of saving WM_CLASS data, save application IDs.
Also, inside the WM we have a much better
infrastructure for tracking windows. In particular, rather
than polling, we can just watch for focus notification on
the display, and window add/remove.
Instead of polling XScreensaver, use DBus to watch org.gnome.Session
which already has an idle time watch.
Now there is no polling at all inside the monitor.
Before, we looked up application data in several ways; the ShellAppSystem
exported just application ids (though it parsed the .desktop files internally),
and we'd create a Gio.DesktopAppInfo object (reparsing the desktop file again),
wrapping that inside a JavaScript AppInfo class, and finally the AppDisplay
would again parse the .desktop file to get the categories.
Also, to look up applications by id previously, we traversed the entire
menu structure each time.
Some qualities such as the NoDisplay flag were not easily exposed in the old
system. And if we wanted to expose them we'd have to change several different
application information wrapper classes.
All in all, it was quite suboptimal.
The theme of this new code is basically "just use libgnome-menus". We do
not call into Gio for app lookups anymore. The new Shell.AppInfo class
is a disguised pointer for the GMenuTreeEntry item.
To fix the caching, we keep a simple hash table of desktop id -> ShellAppInfo.
Add a GConf key for favorites, and API for retrieving them.
Also add shell_app_system_lookup_basename, which we use from
the app monitor to look up WM_CLASS ids.
Track all windows; at the time of opening (and shell startup)
we call into ShellAppSystem to take the WM_CLASS property and
try to find an associated .desktop file.
Add mozilla-firefox to the list of our WM_CLASS workarounds.
Add shell_global_get_screen, since it's often used.
The code here is significantly cleaner if we use the data Metacity
already has cached and validated, rather than talking to X directly.
Also some preparatory work for extending the monitor API by
clarifying the name of the (current) main entry point.
We need to reset the popularity GSList* at start, and everytime we load data about a another activity. This also implies fixing the typo about (activity != -1).

This solves several issues:
- use built-in default so that app monitoring is enabled when schemas are not installed
- don't start/stop timers without checking their previous state
- unreference the default GConfClient
- use #define for the GConf key path
ShellAppMonitor now depends on gmenu to load menus.
Use the menu data from ShellAppMonitor to show a menu list.
GenericDisplay implementations can now have a sidebar area. We
handle keystrokes such as left/right explicitly.
Some internal API changes to account for the fact that a display
can have another filter in addition to the search.
