Oftentimes we want to measure a layout that is as wide or wider than the
current layout's maximal width. In that case we can safely reuse the
current layout.
It's always FALSE.
Note that this patch changes the layout for allocations that are
smaller than 1px, but that's just the default layout that is never
rendered.
The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
You can select something, but moving the focus somewhere else, or bringing up
the context menu makes the selection go away. This makes it impossible to
copy-paste the text.
The reason for this regression is that gtk_label_state_changed was sloppy and
assumed that it would only ever be called when a labels goes insensitive, which
is no longer the case.
The patch fixes things by explicitly checking if the widget is insensitive, and
only resetting the selection in that case, which is the same behaviour we have
for e.g. GtkEntry.
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.
Since GtkLabel is returning invalid natural sizes for now,
in order to test regressions well with the new width-for-height
api, I've temporarily disabled the natural values.
Added a function to update sizegroups in multiple passes, this
way the width and height can be updated in the sizegroups after
querying the extended layout implementor for these.
Implemented this in GtkExtendedLayout, sizegroups should be working reasonably now.
This commit changes gtk_extended_layout_get_desired_size() for
per dimension variants. Furthermore this commit reverts the actions
done in size-groups for now as it needs a different approach.
The natural width/height parameters added to aux_info have been changed
for a per width cache for heights and a per height cache for widths.
gtk-demo is still working, currently sizegroups are not taken
into account as mentioned above - size groups need to be alerted both
when the widths and heights are updated independantly and then that
information needs to repropagate also to other extended layout implementors.
Merged in fixes from the old branch in a patch prepared by Matthias Clasen,
added some fixes of my own to make sure that label wrapping follows allocation
and not requisition at show time (allocate time).
Getting the desired size of a GtkWidget must always be done with
gtk_widget_get_desired_size() and never with
gtk_extended_layout_get_desired_size() directly as the former passes
through size group logic and updates the widget->requisition cache.

Deprecate widget flag macros GTK_WIDGET_STATE, GTK_WIDGET_SAVED_STATE,
GTK_WIDGET_FLAGS, GTK_WIDGET_TOPLEVEL, GTK_WIDGET_NO_WINDOW and
GTK_WIDGET_COMPOSITE_CHILD.
Also deprecate the type macros GTK_WIDGET_TYPE, GTK_OBJECT_TYPE_NAME and
GTK_OBJECT_TYPE which have become redundant.
Instances of GTK_WIDGET_TOPLEVEL are replaced with gtk_widget_is_toplevel,
GTK_WIDGET_TYPE is replaced with G_OBJECT_TYPE, GTK_WIDGET_COMPOSITE_CHILD
is replaced with use of the "composite-child" property and uses of
GTK_WIDGET_NO_WINDOW are adjusted to use gtk_widget_get_has_window.
Uses of GTK_WIDGET_SAVED_STATE and GTK_WIDGET_FLAGS inside GtkWidget are
changed to direct flag usage.
Documentation is updated to refer to gtk_widget_set_has_window and
gtk_widget_get_has_window.
Gail and tests are updated as well.

...and show them in menus when navigating the menu with the keyboard.
This is similar to what other platforms do, and reduces visual clutter.
There is a setting to control this. Most of the work on this patch was
done by Thomas Wood. See bug 588554.
The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.
