Note that this implementation does not respect GDK windows at all. If
your widget requires respecting them, you should write your own
snapshot implementation and not chain up.
We now look at which of get_render_mode, draw or snapshot vfuncs is the
latest to have been overwritten in the class tree and then use that one.
This allows GtkContainerClass and GtkBinClass to override all of them
for without screwing things up.
and gtk_snapshot_render_frame() to be direct replacements for the
old gtk_render_*() functions.
Use them to replace Cairo usage completely in gtk_window_snapshot().
We now try to emulate cairo_t:
We keep a stack of nodes via push/pop and a transform matrix.
So whenever a new node is added to the snapshot, we transform it
by the current transform matrix and append it to the current node.
Unlike other container widgets, GtkStack would allocate its children
prior to moving its windows, which might prevent further valid size
allocation signals to be emitted.
Re-order the size allocation of child widgets to be performed after
moving the GtkStack windows.
Thanks to Owen for spotting the real issue here.

This fixes a DOS where any app can cause all running gtk apps
to use arbitrary amounts of memory.
Originally reported against mate-panel, where running a big slideshow
in eye-of-mate caused increasing RAM usage in mate-panel.

Making sure the surfaces are using the same scale factor makes it more
likely a fast path will be used when pixman gets involved, as pointed
out by Benjamin Otte.

We are currently truncating job names to 255 bytes, because that's the
maximum allowed length of job-name attribute in CUPS. This is a CUPS
limitation that GtkPrintOperation shouldn't need to know, and it
shouldn't affect other backends, that might have other limitations or
even no limitation at all. This has another side effect, that what you
set as GtkPrintOperation:job-name could be different to what you get if
the property is truncated, this is not documented in
gtk_print_operation_set_job_name(). So, I think the job name should be
truncated by the CUPS backend, right before setting the job-name
attribute.

The GApplication platform data may contain a startup ID that on X11
is used to set the startup notification ID when activated. Do the
same on the wayland backend to make startup notifications work for
DBus-activated applications where the DESKTOP_STARTUP_ID environment
variable is not set.

The spec says:
"If <shape> is omitted, the ending shape defaults to a circle if the <size>
is a single <length>, and to an ellipse otherwise."
Make it so.
