2794
2795 We'd like on_canvas_... to get BOTH core and xinput events. Up to
2796 GTK+ 2.16 this is achieved by making only the canvas's parent
2797 GdkWindow xinput-aware, rather than the entire hierarchy.
2798 Otherwise, the proximity detection code in GDK is broken and
2799 we'll lose core events.
2800
2801 Up to GTK+ 2.10, gtk_widget_set_extension_events() only sets
2802 extension events for the widget's main window itself; in GTK+ 2.11
2803 also traverses GDK child windows that belong to the widget
2804 and sets their extension events too. We want to avoid that.
2805 So we use gdk_input_set_extension_events() directly on the canvas.
2806
2807 As much as possible, we'd like to keep doing this, though GTK+ 2.17
2808 is making our life harder (crasher bugs require us to disable XInput
2809 while editing text or using the layers combo box, but disabling
2810 XInput while in a XInput-aware window causes the interface to become
2811 non-responsive).
