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.

G_BEGIN_DECLS
Cache heights-for-range-of-widths instead of height for every width. This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).

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

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.
