This code may have worked when written in 2009, but later gjs commit
b5e467d89aea43a8e32a1138d232c8a32e6b0785 removed the priority
parameter from idle_add.
Now, when running a constantly-updating client (es2gears) on an
embedded platform, _updateRegions() does not get called and I see
unresponsive window decorations.
Update the code to use meta_later_add() like other parts of the
shell, which is actually slightly better in this case anyway.

The smartcard service is put in the foreground in two cases:
1) If password service is disabled by admin configuratoin
2) if a smartcard is inserted
In either case we don't want to ask the user to pick a user from the
userlist. We currently only avoid asking in case 2.
This commit fixes case 1.
https://bugzilla.gnome.org/show_bug.cgi?id=726263
We only want to react to the card the user logged in with, at
the unlock screen. We check "at the unlock screen" by checking
the "reauthenticating" state variable. That variable is the
wrong one, though. It gets set too late, and in some cases, gets
set at the login screen, too. We should be checking this._reauthOnly
instead.
This commit fixes that.

If a user inserts the smartcard they logged in with into the system,

We can't let live (ie, never destroyed) actors undergo GC, because

If we have the following sequence:
cache.getImageContent({ filename: "foo", cancellable: cancellable1 });
cache.getImageContent({ filename: "foo", cancellable: cancellable2 });
cancellable1.cancel();
Then the second load will complete with "null" as its content, even though
it was never cancelled, and we'll see a blank image. Meanwhile, since the
second load simply appends to the list of callers for the second load,
cancellable2 does absolutely nothing: cancelling it won't stop the load,
and it will still receive onFinished handling.
To prevent this from happening, give the actual load operation its own
Gio.Cancellable, which is "ref-counted" -- only cancel it when all the other
possible callers cancel.

At the moment when a file is loaded, we iterate through the list of
pending file loads and ignore any unrelated to the file, then iterate
all the callers of the related file loads and finish them.
In fact, there can only ever be one pending file load related to the
file, and we already know it, so we can avoid the ugly nested loops.
https://bugzilla.gnome.org/show_bug.cgi?id=722149
This commit moves the code around a bit such that the
caller gets allocated up front and then a file load is either
found or created to attach the caller to.
Functionally, the code is the same, it's just now factored in a way
that will make it easier to fix a bug with cancellation later.

The current middle-click action of opening a new window on a new

This is done for properly drawing popup menu when arrow rise is 0 (in
case of background menu).
Normally, the menu with arrow rise set to 0 is drawn properly having
all four corners rounded. But when the source(click/arrowOrigin) is
near screen's edges, one of the corners (depending on source's position
and arrow alignment) is drawn right angled.
This happens because the rounded corners are skipped and right angled
arrow is drawn when arrow origin is close to the edges.(That's why when
arrow-rise is 0, it forms right angled corner).
So, a few condition checks are made to ensure that right angled corner
is not drawn.

Right now we queue populating the user list in the middle of setting

In some cases we load the user list after going back
to main loop and in other cases we load the user list
right away (depending on if accounts service is ready).
In the case we load the user list right away we cause a

which then tries to reset actors which aren't instantiated
yet.
This commit ensures the user list is loaded after the constructor
finishes and the event loop runs irregardless of the accountsservice
state.

One of the most frequent complaints about our launching behaviour is
how we handle terminals. Among all MDI applications, the terminal is
the one that is most likely to have lots of semi-independent windows
opened at the same time, and spawning new windows is much more common.
More so, if it does not support tabs.
Therefore, we special case terminal launchers to always create a new
window. It is an application that most non-technical users will not
use, so chances of them being confused by any special behaviour is
expected to be low.
