... in the case where no change of the DOM tree actually happened.
We don't do anything yet with that information, this patch just
correctly computes it.
When values are computed, they might depend on various other values and
we need to track this so we can update the values when those other
values change. This is the first step in making that happen.
This patch does not do any dependency tracking at all, instead it uses
GTK_CSS_DEPENDS_ON_EVERYTHING as a sort of FIXME.
Both _gtk_css_style_property_print_value() and
_gtk_css_style_property_compute_value() aren't necessary anymore and are
replaced by _gtk_css_value_print() and _gtk_css_value_comptue()
respectively.
This gets rid of the public function
_gtk_css_rgba_value_compute_from_symbolic().
The fallback is now handled using a switch statement instead of letting
the caller pass the function.
This is a reorganization of how value computing should be done.
Previously the GtkCssStyleProperty.compute vfunc was supposed to take
care of special cases when it needed those for computation. However,
this proved to be very complicated in cases where values were nested and
only the last value (of a common type) needed to be special cased.
A common example for this was the fallback handling for unresolvable
colors.
Now, we pass the property's ID along with all compute functions so we
can do the special casing where it's necessary.
Note that no actual changes happen in this commit. This will happen in
follow-ups.
This commit is essentially a large reorganization. Instead of all value
subtypes having their own compute function, there is the general
_gtk_css_value_compute() function that then calls a vfunc on the
subtype.
This hint may be used in text widgets to inhibit their
input methods. The most compelling usecase is calculator
applications, which already have a builtin and better
suited onscreen keyboard.

This improves the layout of the mount operations dialog to:
* Make primary labels bold in all cases
* Lay out the widgets in a grid
* Put space between the two radio groups to distinguish them

We no longer support modifying GdkWindow hierarchies during
expose events. This is not working anymore anyway as the
flush operation now does not push already rendered pixels
in the flushed window from the double buffer to the window.

Avoid copying back partially drawn double-buffer data
when flushing to avoid flicker. This means non double
buffered widgets must draw opaque pixels in its expose
handlers, and that you are not allowed to use direct
rendering (or modify GdkWindow pos/size/order) from
inside the expose handler of a double buffered widget.

gtk_widget_insert_action_group (widget, "foo", NULL) is valid, but
g_action_muxer_insert (muxer, "foo", NULL) is not. Use
g_action_muxer_remove() for that case.
The code was calling _gdk_window_ref_cairo_surface in a few places
where the intent was not to read/write to the surface, but just look
at its type (to e.g. create a similar surface). This is bad, as that
operation causes a flush which may cause unnecessary work and/or
flashing. Instead we just get the impl surface in these cases.
