Currently mutter-window has its own type field, even though the same
information is already present in meta_window.
And while at it get rid of MetaCompWindowType, it is equally redundant.

Commit aa65f94c67 that started passing
cairo_t around broke offsets. Since passing cairo_t makes them
unnecessary, this patches removes them rather than fixing them.
This patch changes API.

With the newest changes to GTK3, some things were changed. This patch
now uses the features introduced in gtk3-compat.h in previous patches.
This patch also introduces a macro named USE_GTK3 that is used to
differentiate between GTK3 and GTK2. Its main use is differenting
between expose and draw handlers for GtkWidget subclasses.
The draw vs expose handlers question is usually handled by using ifdefs
at the beginning and end to set up/tear down a cairo_t and then use it.
However, when the function is too different and too many ifdefs would be
necessary, two versions of the function are written. This is currently
the case for:
- MetaAccelLabel
- MetaFrames

Similar to the region compatibility shim, we will soon need a
compatibility shim around GdkPixmap/cairo_surface_t. For now, the patch
just introduces the compatibility layer.
This patch also does not include the function
meta_gdk_pixbuf_get_from_pixmap() as that function will need special
treatment in GTK3 anyway.

Rename meta_frames_paint_to_drawable() to meta_frames_paint() and make
it take a cairo_t as an argument instead of creating the cairo_t itself.
This patch refactors code for GTK3 changes where code needs to handle
cairo_t and not GdkDrawable arguments.

This commit is in preparation for the work happening in GTK3, which will
use Cairo for drawing exclusively. So it is necessary to move all
drawing code to Cairo. In this commit the "gtk2" code is used for both
gtk2 and gtk3; compatibility with newer versions of gtk3 where different
code is needed will be added subsequently.
For compatibility with older GTK versions, the file gdk2-drawing-utils.h
provides a compatibility layer.
The commit changes the API of libmutter-private.

For functions (but not callback types), '(closure)' is used on the
callback parameter, and takes the name of the parameter which is
the closure/user data.
A maximized window can't be resized from the screen edges (preserves
Fitts law goodness for the application), but it's still possible
to start a resize drag with alt-middle-button. Currently we just
don't let the user resize the window, while showing drag feedback;
it's more useful to let the user "break" out from the resize.
This provides a fast way to get a window partially aligned with
the screen edges - maximize, then alt-drag it out from one edge.
Behavior choices in this patch:
- You can drag out a window out of maximization in both directions -
smaller and larger. This can be potentilaly useful in multihead.
- Dragging a window in only one direction unmaximizes the window
fully, rather than leaving it in a horizontally/vertically
maximized state. This is done because the horizontally/vertically
maximzed states don't have clear visual representation and can
be confusing to the user.
- If you drag back to the maximized state after breaking out,
maximization is restored, but you can't maximize a window by
dragging to the full size if it didn't start out that way.
A new internal function meta_window_unmaximize_with_gravity() is
added for implementing this; it's a hybrid of
meta_window_unmaximize() and meta_window_resize_with_gravity().
Port of the metacity patch from Owen Taylor in bug 622517.

The widget needs to be visible and mapped for GTK3 to deliver expose
events to the widget. This is achieved by making the map function a
no-op and calling gtk_widget_show() instead of just calling
gtk_widget_realize().
Apart from making GTK think the widget is drawable, the effect is the
same.

This way, we can remove the special casing in
meta_frames_paint_to_drawable().
Since the setup in meta_frames_paint_to_drawable() is relatively cheap,
doing it once per rectangle in the expose area should be fine.

gtk_rc_get_style_by_paths() returns NULL if no matching style was
found and the default style should be used. Actually use the default
style in this case.

The hacks we were playing by calling gdk_error_trap_push() and then
resetting the error handler are incompatible with the rewrite of
GDK error traps.
Since the new error code has some features that simplify what we
are doing (like automatically figuring out whether a XSync() is needed)
and because our custom error handler didn't have a lot of a point,
use a separate code path for GTK+ 3.0 builds that just uses the
GDK error traps straight-up without a custom error handler.

Wine sets _NET_WM_USER_TIME_WINDOW to point to an unmapped toplevel;
this was causing much confusion because both the real window and
the unmapped window were in the window stack and mapped back to the
same MetaWindow.

When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.
Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.
