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.
We cannot implement GtkWidgetClass.get_render_node() in GtkContainer
without breaking the fallback path that renders a widget to a single
render node rasterization. For GtkContainer subclasses we should provide
a simple API, similar to gtk_container_propagate_draw(), that gathers
all the render nodes for each child.
commit c3dc0d80f1 fixed the behavior of
GtkContainer widgets requesting an IMMEDIATE resize-mode.
However, GtkWindow has been stomping on resize-mode during realize()
since commit addcc64b9c. The combination
of factors that led to this not being a visible problem during all this
while is uncertain, but this now causes the Shell to continuously try to
relayout its ShellEmbeddedWindow (a GtkWindow subclass).
This commit separates the resize-mode as set internally by GtkWindow
from the one set with the external API, so that GtkWindow only changes
it when it had not been set before by the subclass.

This reverts commit 3eacfa88f2.
Apart from the patch not being correct, we don't want to expose private
structures in header files if we can avoid it.
And this type-checking overhead is not an optimization that is even
measurable.

This fixes an issue where the theme-provided border-width prevents
dialog contents from lining up properly with the headerbar. To make
this work in message dialogs, we have to explicitly set the border-
width of the action area to 0.
We need to disconnect the frame clock when we unrealize (at which
point the old clock is still alive) not in destroy(). Since there
is no common unrealize for containers, trigger this from GtkWidget.
Instead of using 1 global queue for both resizes and style validation,
use 2 queues. This makes the code a lot simpler and fixes a bug where we
could accidentally stop restylying for very delayed restyles.
