Since an StWidget now has children, it needs to allocate those children
properly. Defer to the currently installed layout manager, like Clutter
does.
Now that we have something that allocates children in St, to prevent
double allocations, we use clutter_actor_set_allocation rather than
chaining up to StWidget::allocate.

Since we want to paint children by default in StWidget, we need to
provide a way for custom subclasses to paint their CSS backgrounds
without painting children... introducing st_widget_paint_background.
Additionally, remove any custom paint/pick handlers added by subclasses
of StWidget that just painted their children. This will cause double
painting if left alone.
This also removes the hacky things that some subclasses of StBin did
to prevent their one child to be painted by StBin.

Base ShellStack on StContainer rather than ClutterGroup, so that it
has StWidget-y features (and so we don't have to "cheat" in
shell_stack_allocate()). Implement navigate_focus() to only ever pass
focus into the top-most child, since doing otherwise would be
surprising.

In both, using our allocation directly for the child is wrong; we
should create a new allocation that's our width and height.
In ShellDrawingArea, also need to chain up to parent.

ShellDrawingArea is a size-independent wrapper for a ClutterCairoTexture.
Useful when drawing non-fixed size areas.
ShellStack is a simple container class which holds items
in a completely overlapping Z stack. The main difference
from ClutterGroup is that items will be constrained to
(and allocated) the size of the stack, not getting their
preferred size always.
