Some GtkSettings property are registered by other classes. This leads
to the "interesting" issue that setting GtkSettings:gtk-button-images
requires that the GtkButton class is referenced first - or that a
GtkButton is created.

gtk_paint_layout is utterly broken. Someone needs to fix it so we use
the cairo_t's matrix and don't juggle with both Pango and cairo matrices
everywhere.
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
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.
This includes the addition of a "small" helper function,
_gtk_pango_fill_layout() that ignores color information. This
functionality is not available inside Pango and until that happens, we
need this fix. The bug is filed at:
https://bugzilla.gnome.org/show_bug.cgi?id=624917
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

This commit makes a few massive changes to the extended layout
code:
a.) gtkextendedlayout.c --> gtksizerequest.c
b.) _is_height_for_width --> get_request_mode()
c.) get_desired_size(), get_desired_width(), get_desired_height() -->
get_size(), get_width(), get_height()
This is the first partial commit and only effects portions
of the tree that have already been merged in master (in order to
easily cherry pick this commit).

This fixes the label layout in cases where gtk_widget_size_request()
is called on a label without a following size_allocate(), for instance
when a button state changes.
After fixing height requests this works much smoother, although in
some places pango seems to ellipsize a rotated label when given
the width it requested.
This is the correct support for the opposing orientation for widgets
that support height-for-width, in an interface that was realized as
width-for-height, a height-for-width supporting widget should return
the minimum height for the minimum width when the initial
get_desired_height() is run.
Now (when wrapping), if no "width-chars" was specified for a minimum
width, default to the width guessed by gtk_label_ensure_layout(), small
specified widths will otherwise result in very large height requests.
This commit makes GtkLabel use "max-width-chars" to determine the
desired natural width for wrapping labels as well as all around refactoring
the initially reported values in get_desired_width/height. this also
addresses some issues with rotating ellipsizing text.
