This is so we always have the latest information given by XRandR (or other), and not
rely on Core protocol information that might not have been updated yet.
This is specially visible when a monitor is connected (less frequent) or disconnected
(much more frequent), callbacks on GdkScreen::monitors-changed that call
gdk_screen_get_width/height() could get the screen size previous to the monitor
rearrangement.
So in order to fix this, keep track of the latest monitors information, and calculate
the bounding box in order to know the screen size.

Return values of g_variant_get_child_value() were not unreffed
correctly together with one value returned by g_variant_get().
Use g_variant_get_data() instead of copying each byte separately.

Instead, use the monitor's work area.
This might have unforseen side effects that warrant a later revert, such
as:
- Apparently some WMs assume maximizing when a window is maximum screen
size.
- WMs might not shrink the window by the decorations' size when it tries
to be fullscreen.
- Applications might have buggy size request code that causes weirdly
sized windows.
Scroll valuators were being just appended again and again, leading
to 1) a growing memory issue anytime a device changed 2) the first
scroll valuators to stay permanent on the application lifetime, as
the first stored valuators would always match.

Use info available in Avahi TXT records for creation of gtk printer
and request details when needed (through gtk_printer_request_details()).
If there is a printer advertised on Avahi by a remote CUPS server
try to get its PPD file at first or get its capabilities through an IPP
request if it fails.

When downscaling images, Cairo apparently uses algorithms different
enough to make this test trip over. So add the downscaled image as the
reference instead of downscaling the previous reference image.
Fixes the border-image reftest. For real now.
The new downscaling code in Cairo doesn't allow this test, so we remove
the CSS that made the border downscaled.
So the test does test less now, but it still tests the repeat modes of
border images.
Passive grabs may take pointer focus out of the application, even though
the pointer didn't leave the window, but those events still trigger resetting
of the scroll axes. This is most visible with compiz, and possibly other
reparenting WMs, where passive grabs happen on the WM-managed window that
is a parent of the application toplevel.
As it is not possible to have scrolling happening on the timespan a passive
grab takes action, it is entirely safe for GTK+ to assume none happened if
it gets a crossing event of that nature.

One requirement of .ui files is that each object must have an ID,
even if it is never referred to or directly loaded from the code.
This makes editing .ui files much more onerous than it has to be,
due to the frequent need to invent new IDs, while avoiding
clashes.
This commit makes IDs optional in the XML. They only need to
be provided for objects which are referred to or explictly loaded
from the code. Since GtkBuilder needs IDs for its own internal
accounting, we create IDs of the form ___object_N___ if not
specified in the XML.

This information will be useful in case someone stumbles on a situation
similar to https://bugzilla.gnome.org/show_bug.cgi?id=699574, so we can
figure out where do the crossing events come from or go to easily.
It's been reported in several applications that scrolling feels jerky
since commit cc7b3985b3.
Investigation reported that the combination of passive 4-7 button grabs
on the toplevel and the presence of native subwindows might trigger
too often crossing events from the child window to the toplevel and
back as scroll "buttons" trigger the passive grab. Those crossing events
would reset the scroll valuators rendering scrolling from jerky on
touchpads (where there's intermediate smooth events between the emulated
button ones) to ineffective on regular mouse wheels (where the crossing
event would reset the valuators right before the single smooth scroll
event we get is delivered)
So, only reset scroll valuators when the pointer enters the toplevel
(we only care about this when the pointer is on the window after it's
been possibly scrolling somewhere else), and it doesn't come from an
inferior.
The situations where this happened varied though, the native subwindow
could be one created explicitly by the application, or created indirectly
through gdk_window_ensure_native(). The latter was mainly the case for
evolution (through gtk_selection_set_owner()) and any GtkScrolledWindow
under the oxygen-gtk3 theme (through gdk_window_set_composited())
