You can still hover a mouse on insensitive elements; it's up to the
theme to disable that.
This is in line with the HTML/CSS interpretation of :hover.
Insensitive elements still cannot be clicked.

I have been convinced that it is a bad idea to change the behaviour
at the same time as deprecating it, so go back to respecting the
Gtk/ButtonImages xsetting in buttons created with
gtk_button_new_from_stock() when it is set.
The setting as well as the function are still deprecated, and the
default value of the setting will remain FALSE.
We should set the appropriate style classes when we have
constructed the content and know if it is a label, an image,
or both. Doing this in the convenience constructors is
problematic for language bindings, and misses out when the
content is changed after construction.
We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
Mouse events that we do not handle should bubble up to the parent
widget, so they can be handled there, instead of disappearing inside
the button. Also use GDK_EVENT_{STOP,PROPAGATE} to make return
values clearer.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.

A button is highlighted if the private variable in_button is TRUE.
This variable is set when the pointer is over the button and cleared when
it left the button. When a button is hidden while there is the pointer over
it, GTK generates a leave notification event, in_button is set to FALSE.
But when a button is removed from a container but not destroyed, it is
unrealized and loose its window. It cannot receive the leave notification
event and in_button stay TRUE. So when the button get a new parent it is still
highlighted.

Touch events don't generate crossing events themselves, so
do not rely on these to determine whether the button release
happened within the event window.
GtkButton currently draws itself as active (pressed down) in case we're
pressing and holding the mouse pointer outside its bounds; this is
misleading though, since we won't activate the button unless the mouse
is released inside the button itself.
Fix this by only setting the ACTIVE state flag when the button is
actually pressed down.
