action stuff: stop abusing GLib's namespace Rename our internal GActionMuxer, GActionObserver and GActionObservable classes and interfaces to have names in our own namespace. These classes were originally intended for GIO but turned out to be too special-purpose to be useful there, so we never made them public API but have just been copying them around (without bothering to properly rename them). Now that other people will be copying them out of Gtk, it's even more important to prevent this namespace abuse from spreading further.

Only handle exposes on native window, propagate to children via draw() We now consider non-native windows non-opaque, which means any invalid area in a subwindow will also be invalid all the way up to the nearest native windows. We take advantage of this by ignoring all expose events on non-native windows (which typically means just the toplevel) and instead propagating down the draw() calls to children directly via gtk_container_propagate_draw. This is nice as it means we always draw widgets the same way, and it will let us do some interesting ways in the future. We also clean up the GtkWidget opacity handling as we can now always rely on the draing happening via cairo. We can't really just draw by walking down the widget hierarchy, as this doesn't get the clipping right (so e.g. widgets doing cairo_paint may draw outside the expected gdkwindow subarea) nor does it let us paint window backgrounds. So, we now do multiple draws for each widget, once for each GdkWindow, although we still do it on the same base cairo_t that we get for the toplevel native window. The difference is only the clipping, the rendering order, and which other widgets we propagate into. We also collect all the windows of a widget so we can expose them inside the same opacity group if needed. NOTE: This change neuters gtk_widget_set_double_buffered for widgets without native windows. Its impossible to disable the double buffering in this model.

Introduce gtk_window_get/set_attached_to() gtk_window_get/set_attached_to() is a new API that allows for windows to be attached to a GtkWidget. The attachment is a logical binding between the toplevel window and the widget that generated it; this kind of information is currently used to propagate style information from the widget to the window, but is also useful e.g. for accessibility. https://bugzilla.gnome.org/show_bug.cgi?id=666103

Handle non-baseline supporting subclasses overriding baseline supporting classes If a subclass (say a child of GtkButton) overrides the non-baseline size request methods we need to call these, rather than the new get_height_and_baseline_for_width method. In order to handle this we make the default for this method to be NULL, and instead check at runtime which method to call. If any non-baseline vfunc has changed in a class but the baseline one hasn't, then we can't use the baseline one.

gtk: Add a way to do event capture This patch adds a capture phase to GTK+'s event propagation model. Events are first propagated from the toplevel (or the grab widget, if a grab is in place) down to the target widget and then back up. The second phase is using the existing ::event signal, the new capture phase is using a private API instead of a public signal for now. This mechanism can be used in many places where we currently have to prevent child widgets from getting events by putting an input-only window over them. It will also be used to implement kinetic scrolling in subsequent patches. http://bugzilla.gnome.org/show_bug.cgi?id=641836 We automatically request more motion events in behalf of the original widget if it listens to motion hints. So the capturing widget doesn't need to handle such implementation details. We are not making event capture part of the public API for 3.4, which is why there is no ::captured-event signal.

GtkWidget: Add gtk_widget_insert_action_group() This allows adding a GActionGroup with a given name at an arbitrary point in the widget tree. This patch also adds an internal _get_action_muxer() API. Calling this will create a GActionMuxer associated with the widget. The parent of the muxer will be the muxer of the widget's conceptual parent. For non-menus, that is the normal parent. For menus, it is the attach widget. In this way, we end up with a hierarchy of GActionMuxer that largely reflects the hierarchy of GtkWidget, but only in places that the action context has been requested. These muxers are the ones on which the inserted actions groups are installed. A following patch will add a user of this API.
