GtkTextLayout is internal and unsupported, do not include
it in the gir

Use gtk_cell_size_request_get_size() instead

The doc comments (with annotations) for some of the gdk api are down
in x11/ sources, so we need to scan those too, when building Gdk-3.0.gir.

The goi scanner warns about these nowadays.

And adjust the getters and setters to match. Also include some
documentation by Havoc Pennington about adjustment of size requests
and allocations.

This was added to the test only for the sake of making it
easier to reproduce a bug with scrolled windows (bug 629778).

Expected behaviour: The vertical scrollbar should dissapear as soon
as the required height for the full allocation width (without any
vertical scrollbar) is small enough to not need a scrollbar.

Fixes build if it isn't available. Bug #629748.

No idea of the widget embedding crack has worked in recent versions,
even less now. But at least it now compiles.

Seems commit 7b42d4fe makes
GtkSpinner a direct subclass of GtkWidget but forgets to
update the header file to include gtkwidget.h instead and
declare the instance and class structures properly (assuming
this was just a missed file in the commit).

Otherwise hiding the spinner won't stop it

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.

Originally the GtkSizeRequestIface patches left GtkSizeGroup working
only by bumping the minimum sizes - this commit fixes size groups to take
both minimum and natural requests into account.

A drawing area is not meant to be subclassed from. It also doesn't
provide any feature a spinner would need either.

Doing size requests in expose is broken.

Also remove redundant double definition.

No magic numbers in the code please

GtkWidget alignment properties make this unnecessary in new containers.
