Christian Hergert reported seeing webkit crashes with recent
GTK+. The stacktrace points at the CSS machinery calling into
GtkSettings to get the font name, and then getting surprised
by a property notification that triggers style validation.
To avoid this, query the font name xsetting right away when
we get set a screen.
This will almost certainly overwritten before the widget gets
to the screen, but while we are doing this, we might as well
use the same state that we initialize the widgets state to.
Instead of creating 2 pango layouts in every draw() and on in
_get_content_size (and calling into gettext twice in both cases), just
keep the layouts around and create them in only one place.
I was somehow under the misconception that we'd get GdkEventSettings
events for all the xsettings at startup. That is not in general true,
so we need to make sure that we check for the xsettings value before
we use them, or derived fields. Update all the private getters to
do so; and fix settings_update_font_values() to cope with font
descriptions that might miss the family or size.
I mistakenly assumed that gtk_settings_init was already doing
something to trigger a notify for all properties. It doesn't,
so we have to ensure that settings_update_font_values() is
called at least once.

The fallback code for rendering builtin checks, radios
and expanders was using border parameters. With the generic
gadget borders using the same parameters, this was giving
double borders.
Before commit 6c1bee2377 we were setting an attribute of GtkNotebook
to track the pressed button if the pressed button happened on the
tab itself.
Later in the motion handling code we were checking whether the private
pressed button attribute was set or not in order to handle a tab dnd
or not.
In commit 6c1bee2377 the code changed and set the pressed button
variable unconditionally, which means, a motion event from within the
tab content triggered a tab reordering.
This happened only if the children hierarchy have a widget that bubbles
up both button press event, which sets the private pressed button
attribute; and motion events, which started the tab dnd checking the
private pressed button attribute.
A widget that experienced the regression was GtkListBox.
In order to fix it, set the button pressed variable only when it press
the tab itself, not the content.

Specifically, this URI is not supported on Windows, but GFile will
do its "best" and turn it into GLocalFile("$pwd/network"), with
spectacularly bad results.

We only keep one align flag per child, so it seems odd to
keep separate h/v expand flags. Just keep one expand flag
and interpret it according to orientation. Allow setting
the expand flag for child widgets too, though, so we can
make widget expand without interfering with the recursive
widget expand flag.
Update all callers.
Use the new possibility of expanding child widgets to make
the label of check and radio buttons expand. This fixes
unexpected behavior of these widgets in RTL in some places.
