This commit makes GTK_ALIGN_START/_END pay attention to
the text direction when used in horizontal context.
This is how similar parameters in GtkMisc and GtkAlignment work,
and is generally expected of GTK+ positioning parameters. And this
is new GTK+ 3 api, so it is basically still unused at this point.
If explicit right/left turn out to be needed at some point, we
can expand the enumeration with new values.
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.
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

We can enable on-demand one of the three sections (recommended,
fallback, other apps) or use the special ALL property to display everything
uncategorized.
These properties are also easily bindable from outside.
Like GtkFileChooser does; GtkOpenWith is a generic interface, which is
now implemented by both GtkOpenWithDialog and GtkOpenWithWidget (and in
the future also by GtkOpenWithComboBox).
This patch adds the GtkScrollablePolicy type property to GtkScrollable
and implements it in all subclasses. GtkScrolledWindow observes this
property to make a good guess about when to show/hide scrollbars for
height-for-width content.
Most scrollable children do not do height-for-width *yet* but
most certainly will (toolpalette, treeview, iconview, textview
widgets all TODO), for scrollable widgets that do have a minimum
and natural size, it's important for them to observe the state
of this property in order to properly drive the scroll adjustments
according to the desired GtkScrollablePolicy. This patch makes
GtkViewport do this.
Patch also adds tests/testscrolledwindow.c to display the effects
of this property.
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
Now GtkWrapBox has "horizontal-spreading" and "vertical-spreading" options,
before GtkWrapBox never spread out children across the opposing orientation
(i.e. it never grew "lines" larger then their natural width, they would
act as if set to GTK_WRAP_BOX_SPREAD_START, now they are completely configurable).
h-align = START,END,CENTER,FILL
v-align = START,END,CENTER,FILL
margin-left,right,top,bottom
margin
These should obsolete all such similar properties on
layout containers, GtkMisc, GtkAlignment, GtkContainer::border-width
Margin is outside the size request.
If margin were not outside the set_size_request() it would not work the
same way as container-supplied (child property) padding.
Conceptually set_size_request() forces the value from the subclass
(the original unadjusted request) and then we go on to adjust
the request further by adding the margin.
Made an enum GtkWrapBoxPacking for the expand/fill horizontal/vertical
boolean options... changed xpadding/ypadding to be horizontal-padding
and vertical-padding for a more consistent api and better readablility.
The GtkSubmenuDirection and GtkSubmenuPlacement enumerations
have been deprecated as public API for a while, but are still used
internally in the menu code. Move them to a private header. This
also prevents to generation of GObject boilerplate for these enums.
There were some vestiges of the gtk_{h,v}button_box_set_default_layout()
functionality left. These are gone now. I have also removed
the GTK_BUTTONBOX_DEFAULT value in GtkButtonBoxStyle, but the other
values have been kept at their numeric values, to avoid more serious
ABI change.
