This lets applications block logout and similar actions ahead
of time. Currently only implemented for D-Bus, but Windows has
very similar API since Vista.
This is fairly basic, allowing applications to learn when
the session manager is about to end the session, and possibly
block this. The only implementation at this point is using the
org.gnome.SessionManager D-Bus interface of gnome-session. It should
be straightforward to port the EggSMClient implementations for
Windows and OS X.
An implicit grab is created inside GTK+ when the button is pressed down on a
window. The semantics of wl_shell_surface_resize means that you don't get a
corresponding release event that would ordinarily break the implicit grab. So
we must do it as part of the resize request.
The code for moving the menu into monitor / workarea was duplicated,
once for the push-in scenario and once for without. The problem with
the second case is that we've stored the menu position before adjusting
it. That made us remember an out-of-monitor position that then later
triggered _another_ copy of this code in the size-request implementation.
Unify this to only have one copy of code, and only store the menu
position after adjusting it to be inside the monitor. This fixes both
statusicon menus that get popped up from the panel, outside the workarea,
to not have scroll arrows, and the gedit language menu which was not
placed in the monitor at all after the initial workarea commit.
As a side-effect of this change, we now make large scrolling menus
occupy the full height of the workarea. Before this change, we were
keeping either the top or bottom edge put while shrinking the menu
to fit in the monitor.

Instead of "attribute with later start index wins, make sure the
attribute list that is merged from takes precedence. This now gives the
multiple attribute lists we use in the label an order:
1) gtk_label_set_attributes()
These attributes override everything. It's what the function's there
for after all.
2) markup of label
Other user-specified attributes come next.
3) attributes for links
When we apply custom attributes on parts of the text, we put them
last. We don't want to mess with what the user does. Also, we change
color and underline, so we usually have something to show.
- Don't compute link color attributes until layout creation
This is useful as a performance enhancement, because we don't have to
lookup the property after setting the text, so multiple markup sets
don't cost style lookups.
- Don't merge attrs into effective_attrs
We do this when applying link colors now. Keeping them separate allows
invalidating them separately.
Instead of getting confused by applied underline or color tags in the
regular markup, we store the link start/end when we actually parse the
text. As a bonus, we can avoid rescanning links when creating the
markup.
As previously announced, key snooping is something that we should not
support in GTK. In particular because AT-SPI made every key press a
synchronous DBUS call / spawned a nested main loop with the key
snoopers. This breaks responsiveness, order of key presses and internal
consistency when the AT decides to remove key events.
This patch modifies GtkPrinterOptionWidget to support loading them
again. It also allows the user to enter values from the dropdown list
to select the item.
