Carlos Garnacho 59a8106373 gdk: Drop supports_multidevice API 
Crossing events are now detached from widget state, all tricky consequences
from getting multiple crossing events are now somewhat moot. Resort to sending
all generated crossing events, and drop this barely (ever?) used API.

/**
* GtkWidgetClass:
* @parent_class: The object class structure needs to be the first
* element in the widget class structure in order for the class mechanism
* to work correctly. This allows a GtkWidgetClass pointer to be cast to
* a GObjectClass pointer.
* @activate_signal: The signal to emit when a widget of this class is
* activated, gtk_widget_activate() handles the emission.
* Implementation of this signal is optional.
* @show: Signal emitted when widget is shown
* @hide: Signal emitted when widget is hidden.
* @map: Signal emitted when widget is going to be mapped, that is
* when the widget is visible (which is controlled with
* gtk_widget_set_visible()) and all its parents up to the toplevel
* widget are also visible.
* @unmap: Signal emitted when widget is going to be unmapped, which
* means that either it or any of its parents up to the toplevel
* widget have been set as hidden.
* @realize: Signal emitted when widget is associated with a
* #GdkSurface, which means that gtk_widget_realize() has been called or
* the widget has been mapped (that is, it is going to be drawn).
* @unrealize: Signal emitted when the GdkSurface associated with
* widget is destroyed, which means that gtk_widget_unrealize() has
* been called or the widget has been unmapped (that is, it is going
* to be hidden).
* @root: Called when the widget gets added to a #GtkRoot widget. Must chain up
* @unroot: Called when the widget is about to be removed from its #GtkRoot widget. Must chain up
* @size_allocate: Signal emitted to get the widget allocation.
* @state_flags_changed: Signal emitted when the widget state changes,
* see gtk_widget_get_state_flags().
* @direction_changed: Signal emitted when the text direction of a
* widget changes.
* @grab_notify: Signal emitted when a widget becomes shadowed by a
* GTK+ grab (not a pointer or keyboard grab) on another widget, or
* when it becomes unshadowed due to a grab being removed.
* @get_request_mode: This allows a widget to tell its parent container whether
* it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
* %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
* %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH means the widget prefers to have
* #GtkWidgetClass.measure() called first to get the default width (passing
* a for_size of -1), then again to get the height for said default width.
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
* width-for-height geometry management for said widget and is the
* default return.
* It’s important to note that any widget
* which trades height-for-width or width-for-height must respond properly
* to a for_size value >= -1 passed to #GtkWidgetClass.measure, for both
* possible orientations.
* @measure: This is called by containers to obtain the minimum and natural
* size of the widget. Depending on the orientation parameter, the passed
* for_size can be interpreted as width or height. A widget will never be
* allocated less than its minimum size.
* @mnemonic_activate: Activates the @widget if @group_cycling is
* %FALSE, and just grabs the focus if @group_cycling is %TRUE.
* @grab_focus: Causes @widget to have the keyboard focus for the
* #GtkWindow it’s inside.
* @focus: Vfunc for gtk_widget_child_focus()
* @set_focus_child: Sets the focused child of a widget. Must chain up
* @move_focus: Signal emitted when a change of focus is requested
* @keynav_failed: Signal emitted if keyboard navigation fails.
* @get_accessible: Returns the accessible object that describes the
* widget to an assistive technology.
* @query_tooltip: Signal emitted when “has-tooltip” is %TRUE and the
* hover timeout has expired with the cursor hovering “above”
* widget; or emitted when widget got focus in keyboard mode.
* @compute_expand: Computes whether a container should give this
* widget extra space when possible.
* @css_changed: Vfunc called when the CSS used by widget was changed. Widgets
* should then discard their caches that depend on CSS and queue resizes or
* redraws accordingly. The default implementation will take care of this for
* all the default CSS properties, so implementations must chain up.
* @system_setting_changed: Emitted when a system setting was changed. Must chain up.
* @snapshot: Vfunc called when a new snapshot of the widget has to be taken.
* @contains: Vfunc for gtk_widget_contains().
