Since Havoc's patches introducing the GtkWidget halign/valign
properties, fill should always be TRUE. If the widget should
not fill its allocated space then it should set the halign or
valign properties for that purpose.
This also consequently fixes bug 634592.
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

An event filter may add or remove filters itself. This patch does
two things to address this case. The first is to take a temporary
reference to the filter while it is being used. The second is
to wait until after the filter function is run before determining
the next node in the list to process. This guards against
changes to the next node. It also does not run functions
that have been marked as removed. Though I'm not sure if this
case can arise.

In the current introspection data, the various gtk_radio_button_new_*
constructors take an existing group or widget. These all allow passing a NULL
widget or group list, so that it becomes easy to build a radio button list in a
loop (pass in None the first time, and the previously created button in all
other iterations).
Add the missing "allow-none" tag to the introspection data, so that this will
also eventually work for GIR users. NB that it does not actually work for some
constructors yet (like new_with_label_from_widget()) due to
https://bugzilla.gnome.org/show_bug.cgi?id=561264.

Since what we are doing is turning an icon with alpha into a
no-alpha icon + mask for legacy window managers, it makes more sense
to use the system visual than the window's visual, which might
be ARGB.

Now gtk_widget_size_allocate() unsets the resize_needed flags
before returning, essentially this means that any widget that
has a queued resize and is allocated before resize time, including
queued resizes from inside a size_allocate() method will be
cancelled.
when GtkEntry had visible windows, it was never noticed that we always
draw the frame, because the text_area window would cover it if
draw_frame was FALSE.
