- don't poke at the children's background pattern at draw time, but just
call gtk_render_background()
- we should propagate rendering of the background to the overshoot
window when the state flags or the style changes, or it won't respond
to e.g. focused/backdrop changes correctly

GTK_CSS_DEPENDS_ON_EVERYTHING was used as a placeholder when
implementing dependencies. Now that dependencies are completely
implemented, it's no longer necessary.
... 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.
