Dan Winship b8126ce3af * generator/ClassBase.cs (ParseImplements): record both managed
and unmanaged interface declarations.
	(Implements): check recursively

	* generator/ObjectGen.cs (Generate): output managed interfaces

	* gtk/Gtk.metadata: make Container implement IEnumerable

	* gtk/Container.custom (GetEnumerator): implement (a simplified
	form of Children).
	(AllChildren): add this (which accumulates the results of
	Forall()).
	(ForAll): mark ForAll(bool,CallbackInvoker) obsolete and add a
	ForAll(bool,Gtk.Callback) overload to replace it.

	* sample/PolarFixed.cs: new silly but fully-functional demo of
	how to subclass container.

	* sample/CustomNotebook.cs: kill this, since it was really
	complicated, and never fully functional.

	* sample/GtkDemo/DemoImages.cs (ToggleSensitivity): Use foreach
	directly on the container, rather than on its .Children.

<summary>Base class for widgets which contain other widgets</summary>
<remarks>
<para>
A Gtk# user interface is constructed by nesting widgets inside widgets. <see cref="T:Gtk.Container" /> widgets are the inner nodes in the resulting tree of widgets: they contain other widgets. So, for example, you might have a <see cref="T:Gtk.Window" /> containing a <see cref="T:Gtk.Frame" /> containing a <see cref="T:Gtk.Label" />. If you wanted an image instead of a textual label inside the frame, you might replace the <see cref="T:Gtk.Label" /> widget with a <see cref="T:Gtk.Image" /> widget.
</para>
<para>
There are two major kinds of <see cref="T:Gtk.Container" /> widgets in Gtk#. Both are subclasses of the abstract <see cref="T:Gtk.Container" /> base class.
</para>
<para>
The first type of <see cref="T:Gtk.Container" /> widget has a single child widget and derives from <see cref="T:Gtk.Bin" />. These containers are decorators, which add some kind of functionality to the child. For example, a <see cref="T:Gtk.Button" /> makes its child into a clickable button; a <see cref="T:Gtk.Frame" /> draws a frame around its child and a <see cref="T:Gtk.Window" /> places its child widget inside a top-level <see cref="T:Gtk.Window" />.
</para>
<para>
The second type of <see cref="T:Gtk.Container" /> can have more than one child; its purpose is to manage layout. This means that these containers assign sizes and positions to their children. For example, a <see cref="T:Gtk.HBox" /> arranges its children in a horizontal row, and a <see cref="T:Gtk.Table" /> arranges the widgets it contains in a two-dimensional grid.
</para>
<para>
To fulfill its task, a layout <see cref="T:Gtk.Container" /> must negotiate the size requirements with its parent and its children. This negotiation is carried out in two phases, size requisition and size allocation.

<remarks>
<para>
Typically used for simple containers such as <see cref="T:Gtk.Window" />, <see cref="T:Gtk.Frame" />, or <see cref="T:Gtk.Button" />; for more complicated layout containers such as <see cref="T:Gtk.Box" /> or <see cref="T:Gtk.Table" />, this function will pick default packing parameters that may not be correct. So consider functions such as <see cref="M:Gtk.Box.Packstart" /> and <see cref="M:Gtk.Table.Attach" /> as an alternative to <see cref="M:Gtk.Container.Add" /> in those cases. A <see cref="T:Gtk.Widget" /> may be added to only one <see cref="T:Gtk.Container" /> at a time; you can not place the same widget inside two different containers.

<param name="child">an object of type <see cref="T:Gtk.Widget" /></param>
<param name="evnt">an object of type <see cref="T:Gdk.EventExpose" /></param>
<remarks>
<para>
When a <see cref="T:Gtk.Container" /> receives an expose event, it must send synthetic expose events to all children that do not have their own <see cref="T:Gdk.Window" />s. This function provides a convenient way of doing this. A <see cref="T:Gtk.Container" />, when it receives an expose event, calls <see cref="M:Gtk.Container.PropagateExpose(Gtk.Widget,Gdk.EventExpose)" /> once for each child, passing in the event the <see cref="T:Gtk.Container" /> received.
</para>
<para>
<see cref="M:Gtk.Container.PropagateExpose(Gtk.Widget,Gdk.EventExpose)" /> takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event.
</para>
<para>
In most cases, a <see cref="T:Gtk.Container" /> can either simply inherit the expose implementation from <see cref="T:Gtk.Container" />, or do some drawing and then chain to the expose implementation from <see cref="T:Gtk.Container" />.

<para>
In principle each <see cref="T:Gtk.Widget" /> in the chain should be a descendant of the <see cref="T:Gtk.Container" />, but this is not enforced by this method, since it is allowed to set the focus chain before you pack the widgets, or have a widget in the chain that is not always packed. The necessary checks are done when the focus chain is actually traversed.
</para>
<para>
If no focus chain has been explicitly set, gtk# computes the focus chain based on the positions of the children. in that case, gtk# stores <see langword="null" /> in focusable_widgets and returns <see langword="false" />.
