The changes from commit b4f5f1e461 and b394d184cc increased the
instructions required for the fade fragment shader. This is over the limit
for some hardware (like intel gen3), which causes the driver to fallback
to software rendering for the shader. The result is that painting a scrollview
that has a fade effect takes around 30 (!!) seconds.
So lets go back to the old effect for 3.8 until we find a solution.

There's large performance issues with both the blur and desaturation
that make the screen shield hard to use on slower computers, and this
has always been a temporary stopgap until the user can pick a different
image for the lock screen.

Right now, if multiple messages come in, they just sort of
clobber each other.
This commit sets up a message queue, and introduces pauses
long enough for the user to hopefully be able to read those
messages.

GDM sends a reset signal after verification succeeds
so that a user-switched login screen can prepare for
the next time it's going to be used.
The unlock screen treats resets as failures, though.
This means, on success, we're emitting "failed" and
clearing any last second messages.
This commit changes the unlock code to ignore resets from
GDM after successful verification.
https://bugzilla.gnome.org/show_bug.cgi?id=694688
Right, the common code between the login screen and
the unlock screen handles clearing the user verifier
when GDM sends a reset.
We don't actually always want to clear the messages on
reset in the unlock case, though, so doing it implicitly
is problematic.
This commit moves the clear() call from the common code
to the specific reset handlers.

Since we drop our event handler, we won't see ever the release event
from the button press, so unset the flag so it doesn't muck with the
next time somebody takes a grab.

Getting fullscreen window tracking right in GNOME Shell turned out to
be very hard, because it depended on details both how Mutter handled
fullscreen windows and the exact timing of that. Fullscreen tracking
and auto-minimization of fullscreen windows that lose their fullscreen
status has thus been implemented in Mutter: use that.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
Previously when a client requests that a window should be docked the
shell would reparent the socket window onto the stage's window and
then use ClutterX11TexturePixmap to get a texture to represent the
window. This will not work if Clutter is no longer using the X11
winsys for example if it becomes its own display server. Instead this
patch leaves the socket window as a child of the root window and lets
mutter create a MetaWindow out of it. If Mutter is acting as a display
server then this mechanism will still work via the headless x server.
The ShellGtkEmbed instance now registers for notification of the
‘window-created’ signal of the display so that it can find the
MetaWindow that gets created to represent the socket window. When this
window is found it is prevented from being displayed on the screen by
setting the actor's opacity to 0. An input shape is then set on the
window to prevent it receiving any input.
Instead of being a subclass of ClutterX11TexturePixmap, ShellGtkEmbed
is now a subclass of ClutterClone. When the MetaWindow is found for
the socket window the clone's source is set to the invisible actor for
the window so it can be displayed in the panel as before.
The ShellEmbeddedWindow no longer needs to know what the stage is
because it no longer reparents the socket window. Therefore the
ShellTrayManager doesn't need to know the stage either so
shell_tray_manager_manage_stage has been replaced with just
shell_tray_manager_manage_screen.

To create a new workspace by dropping on the placeholder, we move all
the windows down one workspace and then wait for _checkWorkspaces() to
automatically create the empty one at the end.
This means that, from the implementation POV, the new workspace is not
the one created by DND but it's the last one, and this detail was exposed
in the UI because the animation was applied on that one.
Fix that by starting the animation manually from the DND code, and then
blocking the animation from happening when the new workspace is created
with a flag.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
DND of windows has a lot of side effects, including the possibility of
current workspace disappering from under our feet. We need to account
for that when trying to activate it.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
This happens in the case of Workspace/WorkspaceThumbnail: they call
meta_window_change_workspace_by_index(), which fires window-removed
on the old workspace, thus destroying the window clone.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
Windows can be restacked at any time, including when the stackAbove
property of the window clone is being dragged, and thus parented to
the uiGroup. To do stacking properly, we need to skip it for the duration
of the drag, and sync it again at the end (which is already done by
mutter because of the workspace change)

ClutterBinLayout uses the maximum width/height of all children in
size requests and positions children according to the expand/align
properties. This means that the vertical position of folder popups
is not considered in size requests, so if the main view is smaller
than a folder popup's height and offset, the popup will be truncated
and/or mispositioned. Fix those cases by using a custom LayoutManager
that behaves like ClutterFixedLayout for height requests and like
ClutterBinLayout otherwise.
https://bugzilla.gnome.org/show_bug.cgi?id=694371
The login dialog has a maximum height set to prevent the user list
from growing indefinitively. However this approach fails if the
monitor height is smaller as said maximum, so add some additional
top/bottom padding to make sure there's some whitespace above/below
the user list in that case as well.

Commit 7b3a689aad changed the border-radius of the hover effect
to match the prelight effect, but not the focus indication, so
the focused item now changes corners on hover. Fix this by using
a consistent border-radius.

We need to look at the duration of the current step of the slideshow
to determine when to next queue an event, rather than the full slideshow
duration.
