We only support the preview state for checkboxes for GtkButton
because it gave problems when used in treeview where the prelight
state affects all checkboxes in the row.
When GtkPrinterFunc always returns FALSE, for example when looking for
a non existent printer, if print list is done for all backends or print
backend status is UNAVAILABLE, gtk_enumerate_printers() finishes with an
empty backend list and destroy function is never called. We need to
check the backend list again after calling list_printers_init for all
backends and finish the enumeration if it's empty.

As we don't give out information about the group or level when
giving back keycodes, we should prioritise group-0, level-0, followed by
level-0 only, and then any keycodes.
This fixes "q" being pressed when the Wacom tablet code in
gnome-settings-daemon is supposed to generate an "a" ("uk" keymap
in group-0, "fr" in group-1).

When the scrolled window has a frame (and the scrollbar is within the
bevel), we should take into account the CSS border/padding of the frame
and offset the scrollbars junction rendering with it.
It seems XP doesn't handle drawing non-alpha theme parts
on alpha destinations. We fix this by using alpha bitmaps only when
needed.
However this means any non-drawn area by the theme part is now draw
black, so we must take more care to only draw where the theme part draws,
so we find the theme part size when available.
We now store the symbolic colors as a GtkCssValue which means that
we can reuse the color when resolving and storing the color in
the computed values in the style context.
Additionally we keep a last_resolved GtkCssValue cache in the
GtkSymbolicColor, and if resolving the color returns the same as
last time we reuse the old value. This further increases sharing
of Css Values.
va_copy() is not universally available, and we already have a G_VA_COPY
macro that emulates the behaviour of va_copy() when it's not available, or
simply calls va_copy() if it's there
Also, in places where we're computing a new CssValue based on an
old one, make sure that if nothing changes we're returning a reference
to the old one, rather than creating a new identical instance.
Some people destroy their widgets in ::response, so trying
to access dialog internals from the class handler that is
running afterwards has the potential to cause problems.
Instead, we can reset the ::show-editor property every
time we map the dialog.
