Also clean up and rearrange the code.
As a side-effect, the no-longer-existing stipple attributes
are dropped.  Update test results to match.

And some code rearrangement.

Replace the factory for entry and spin button with
gtk_widget_class_set_accessible_type() calls, and move then
to the GtkAccessible namespace.

The a11y selection tests poke the selection on unrealized
labels. Don't spew warnings in this case.

GtkLabel passes this now.

The label accessible port dropped the no-longer-existing
stipple attributes; so update the expected test results to match.

Unfortunately, we still keep a copy of the text around, for
::insert/::delete signals; those emissions need to be moved to
GtkLabel itself.

This function translates the fg/bg color into atk attributes.

These functions are implementations of the AtkText api on top
of a PangoLayout, and are intended to replace GailTextUtil.

Since gtkpango.h is a private header, also remove the individual
inclusion prohibition.

The new test is much smaller, and the results have been carefully
looked at; GtkLabel gets it right, the others don't.

Also, temporarily include some code that dumps out useful information.

Make the get_property switch look a little nicer.
We export these functions privately for use in the label
accessible implementation later on.

Fixes underallocation warnings

It's not exposed in AT-SPI so we don't need it.

AT-SPI doesn't expose them, so there's no need to keep them.

The consensus of the accessibility team was that 'color chooser'
fits best for this. Update tests to match.

The consensus of the accessibility team was that this is
an animation. Update tests to match.

We always have the textutil now, so remove some NULL checks.
Also, never say 'State is defunct' again...

When setting properties that require recalculating the label
text, freeze notification until the label is properly updated.
This fixes bug 126797.

This removes a horrible workaround for bug 126797. To prevent
picking up accidental markup in label texts, the label accessible
is listening for window creation and mapping and defers initializing
its text until then.

This tests a problem that was first noticed in 2003, in
bug 126797: The text of a label accessible is not properly
updated when the label switches from !use-markup to use-markup.

Needless to say, these tests still fail.

These unfortunately all fail really miserably, currently.

A first experimental conversion from the gail namespace to gtkaccessible.
At the same time, use gtk_widget_class_set_accessible_type() to register
the accessible type for GtkLabel.

The function was unused and unnecessary.

This duplicates the current test with a GtkTreeStore instead
of a GtkListStore.

Avoid many unnecessary list iterations by using a hash table
to store cell infos, and caching row and column counts. Based
on patches by William Jon McCann, bug 554171.

tree-performance results:

before:  (MINPERF:large tree test with a11y: 9.18531sec)
after:   (MINPERF:large tree test with a11y: 0.923463sec)

for comparison, without accessibility:
(MINPERF:large tree test: 0.016179sec)

This test creates a treeview with a few columns and a liststore,
and then populates it with a 1000 rows.
