Now the window background is a cairo_pattern_t. The backends will try to
set this as good as they can on the windowing system, but no guarantees
are made on wether the windowing system supports the pattern.
Also gets rid of GDK_NO_BG as undefined behavior is not a good idea to
support, and GDK_NO_BG effectively made the window's contents undefined.
It wasn't effectively used in GTK anyway.
This removes gdk_window_shape_combine_mask() and
gdk_window_input_shape_combine_mask(). GdkBitmap is going away and a
replacement exists via the combine_region() functions and
gdk_cairo_region_create_from_surface().
Replace gtk_widget_shape_combine_region() with
gtk_widget_shape_combine_mask() and
gtk_widget_input_shape_combine_region() with
gtk_widget_input_shape_combine_mask().
As GdkBitmap is going away, and the region equivalents already exist,
this seems like pretty much the default step to take.
Includes code to fix up the users.
The function converts the given surface into an alpha bitmap mask. This
is mostly useful for setting shape regions.
Also adds a new internal function _gdk_cairo_surface_extents() that
computes a surface's extents.
Dealing with bare pointers is problematic for language bindings,
using interned strings is much more straightforward and more than
good enough for what is needed here.

With gtk_show_uri, global configurability of link activation has
moved to GIO/gvfs. For local overrides, GtkLinkButton has the ::clicked
signal, and GtkAboutDialog gets an ::activate-link signal.

* add per-display gdk_x11_display_error_trap_push()
(X11-specific because gdk_error_trap_push() probably
should have been)
* make gdk_error_trap_push() handle only GDK displays
not displays opened without a GDK wrapper
* make gdk_error_trap_pop() and gdk_x11_display_error_trap_pop()
automatically sync only if needed, so manual gdk_flush() is not
required
* add gdk_error_trap_pop_ignored() which just asynchronously
ignores errors, so never needs to sync
* add G_GNUC_WARN_UNUSED_RESULT to plain pop(), because
if you use plain pop() and don't need the return value,
the async gdk_error_trap_pop_ignored() should be used
instead. This results in lots of warnings to clean
up in a later patch.
The main objective here was to avoid the need to sync just
to ignore an error. Now, syncing is automatic, and only
happens when we need to know the error code.

When grouping height-for-width trading widgets (wrapping labels for instance)
vertically; the height for the minimum width will always be used for the entire
group... this patch warns about this in the docs.
This was the last exported variable; it wasn't multihead safe,
and there's easy replacement with gdk_display_get_default().
Also drop the GDK_DISPLAY() macro which was just a wrapper around
the variable.
With the demise of GtkList and GtkTree, it has GtkMenuItem as sole
derived class, and is not really adding any value as a separate class.
Its few useful features have been merged into GtkMenuItem.
Bug 629104
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
Having variables exported from a DLL is slightly painful and
potentially error-prone on Windows, so let's try get rid of them now
when we can. Starting with these.
