Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
This reverts commit f4438a1ffc.
The calculation of the delta between parent and child widget
is required in order to automate height-for-width and width-for-height
requests for various GtkBin widgets.
GtkButton, GtkCheckButton, GtkRadioButton, etc, all have different
requests for space around the content which can not be satisfied
with a simple calculation of GtkContainer border-width.
What is this bin doing with all these crazy deltas? Company does:
<Company> that can safely be removed
<Company> in general, code that isn't obvious can either be understood
<Company> with a bit of thinking or it can be removed
<Company> if in doubt, go for the 2nd of those :)
Most GtkBin subclasses override this strange garbage anyway, so it's
not like this code is ever *run*, per se. Just make it proxy directly
to the child, and hope nothing goes wrong.
Implement get_preferred_width, get_preferred_height, and size_allocate.
This allows GtkBin subclasses to be quick and easy, without the
author doing the subclassing to have to do much work.
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.
Since "->adjust_size_request()" was added, it became important for GtkBin's
generic height-for-width implementation to further check the requests
using this vfunc.
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".
In GtkBin and GtkWidget we tried to provide handy defaults that
call get_width if there's no get_width_for_height and
get_height for get_height_for_width.
However, they used the wrapper API on GtkSizeRequest instead of
chaining directly to the other method implementation.
This could result in all kinds of surprising behavior, for example,
get_width_for_height() would now already include the effects of set_size_request().
If nothing else it's inefficient. But it's just conceptually wrong,
because to chain to another implementation, we should call the other
implementation, not call a wrapper around the other implementation
(when we're already inside a previous invocation of the wrapper,
i.e. compute_size_for_orientation() ends up reinvoking itself
in the same orientation on the same object which it pretty
likely isn't intending to do)

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 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.
Instead of implementing ->get_desired_size() on GtkBin, which
cant really be done because border widths are in the domain of
the concrete subclasses; here we implement only the get_height_for_width
and get_width_for_height apis - GtkBin subclasses whom might have a
variable border width depending on allocations need to write their
own height-for-width implementations.
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.
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.
