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.

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

Initial support for baselines This modifies the size machinery in order to allow baseline support. We add a new widget vfunc get_preferred_height_and_baseline_for_width which queries the normal height_for_width (or non-for-width if width is -1) and additionally returns optional (-1 means "no baseline") baselines for the minimal and natural heights. We also add a new gtk_widget_size_allocate_with_baseline() which baseline-aware containers can use to allocate children with a specific baseline, either one inherited from the parent, or one introduced due to requested baseline alignment in the container itself. size_allocate_with_baseline() works just like a normal size allocation, except the baseline gets recorded so that the child can access it via gtk_widget_get_allocated_baseline() when it aligns itself. There are also adjust_baseline_request/allocation similar to the allocation adjustment, and we extend the size request cache to also store the baselines.

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.
