Saves ~6MB of memory per application in the Adwaita I am using - at
least until the app starts using all the images in the theme, because
the code doesn't discard images yet once they were loaded.

This is essentially a GtkCssImage for a cairo_surface_t and is a pretty
much straight up copy of GtkCssImageUrl. But we want to implement lazy
loading and animations, so GtkCssImageUrl is going to gain new
features...

I'd like to use it when printing the value, but I haven't found a way to
do that sanely yet, as I'd need to be able to print relative paths for
make check to work (otherwise the srcdir would blow things up). And we
use a GString to output to, so there's no way to attach a base dir to
that.
If anyone has an idea how to achieve that, poke me. Having the real
filename in debug prints sounds like a very good idea to me.

Commit ddceddaa84 removed the call to
gtk_style_context_set_background() in favour of always rendering it with
gtk_render_background() during the draw vfunc.
This has the side effect of making the backing window always
transparent, which blocks GTK from applying some optimizations during
the paint cycle. The result is that, especially in clutter-gtk
applications, scrolling performance gets really bad.
This commit partially reverts ddceddaa84
and changes the code so that both gtk_style_context_set_background() and
gtk_render_background() are called

gtk_tree_drag_source_drag_data_get's GtkSelectionData argument should not be
marked as (out) because:
a) GtkSelectionData is semi-private (it's declared in gtkselectionprivate.h),
and thus gobject-introspection has no knowledge of its fields or its size.
There is thus no way for language bindings to allocate GtkSelectionData.
b) Even if it was possible for language bindings to allocate GtkSelectionData,
a zeroed-out instance thus created would not be usable with
gtk_tree_drag_source_drag_data_get. As far as I can tell, you need to
initialize its "target" member to the GdkAtom of "GTK_TREE_MODEL_ROW".
Language bindings have no way of knowing this, of course.

This is akin to commit cfb09e5654 in the gtk-2-24 branch;
the last_folder_uri is no longer being used for anything meaningful, so we
remove it altogether.

This is a quickfix to keep things working.
It turns out GtkWindow assumes it can do sizing operations while not
being visible, or while in the process of show()ing/hide()ing itself.
And commit b495ce54 broke these operations.
Figuring this properly requires some more thinking and restructuring on
my part, so for now we relax the requirement of visiblility enough for
these things to start working again.
The code is always instantiating this schema at a fixed location, so why
is it relocatable?
Add a path so that it shows up properly in dconf-editor, and from the
gsettings commandline tool.

-Rename the "libgail" projects to gtka11y, for consistency with the
autotools builds
-Update the projects completion in gtk/a11y/Makefile.am, as the sources are
now listed under $(libgtka11y_la_SOURCES) instead of $(libgail_la_SOURCES)
An instance of GtkAdjustment may be used by another instance after
the spin button widget is destroyed. In that case, the function
gtk_spin_button_accessible_value_changed() will be called with an
invalid argument. This situation is often caused when one use
GtkCellRendererSpin widget. To avoid invalid call of the function,
the signal handler for the "value-changed" signal should be disconnected
when the spin-button widget is destroyed.
Using g_signal_connect_object achieves just that.

Since 16195ad the “expand” property is always set to FALSE when a
column is resized. This commit takes a different approach and enables
“expand” whenever the column is wide enough. An appropriate
“fixed-width” (so that the desired width is achieved after expanding) is
calculated using equations that are explained in the code.
https://bugzilla.gnome.org/show_bug.cgi?id=691751
Rewrites gtk_tree_view_column_request_width() and
gtk_tree_view_size_allocate_columns() to respect the minimum and natural
sizes that are already being returned by
gtk_cell_area_context_get_preferred_width().
The convoluted logic explained (not!) by this comment has been removed:
“Only update the expand value if the width of the widget has changed, or
the number of expand columns has changed, or if there are no expand
columns, or if we didn't have an size-allocation yet after the last
validated node.” This logic seems to have been a workaround for the
“jumping” behavior fixed in 16195ad and is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=691751
Removes the hidden “resized-width” and “use-resized-width” properties
from GtkTreeViewColumn and instead uses the “fixed-width” property to
serve the same purpose. “fixed-width”, if set, will now override the
auto-sized width (-1 is now a legal value meaning “not set”).
Additional “cleanups” in this commit:
1. When the user resizes the column the “expand” property is now also
set to FALSE, in order to prevent the column from suddenly jumping to a
different width when the window is resized.
2. The code that translated mouse movement to column sizes has been
simplified:
the change in column width is now calculated directly from the distance
the mouse cursor has traveled. Weird behavior that might have happened
previously if the position of the column changed during resizing, is now
prevented.
3. There was some lengthy logic handling the keyboard shortcuts used to
resize treeview columns, which would call gtk_widget_error_bell() once
the minimum or maximum width was reached. Instead of rewriting these
checks I simply set the “fixed-width” property to what was requested,
relying on the fact that it is already clamped between the minimum and
maximum width during size allocation.
I will greatly surprised if anyone notices the missing error bell.

Splits up size_request() so that the height calculations are only done
when get_preferred_height() is called and the width calculations are
only done when get_preferred_width() is called. Since
get_preferred_width() does not change the treeview->priv->width value,
treeview->priv->prev_width will always be equal to it and can therefore
be removed. The only place where prev_width was used is a block in
gtk_tree_view_size_allocate(). This block seems to be adjusting the
horizontal scrollbar to account for treeview->priv->width having been
changed in size_request() and should no longer be necessary. A similar
block immediately above it seems to already account for the width change
in size_allocate().

After “validation” (i.e., background size calculations) of some cells,
size_request() was called here to update the internally cached size of
the treeview. Apparently not updating the sizes leads to some kind of
“inconsistency” that messes with top_row_to_dy(). In the GTK3 model for
size allocation, things are more complicated. The treeview can’t just
go ahead and calculate its own size any more; instead it reports both a
“minimum” and a “natural” size, and it doesn’t know what size it will
actually get until size_allocate(). It may be necessary to update
top_row_to_dy() to deal with not knowing the exact size.
