I want to get away from the ability to have 0-length arrays, all css
arrays are single element.
Even if the element is "none", it is still a "none" element.
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.
Equality tests are done with _gtk_css_value_equal(). There is no need to
do it per-property, equal values will still be equal.
This essentially reverts 24f5d54329e028347bd76af42e86ed190c1229a2 and
92c7a7171e1240b6d961ee5b6f9ab6b596e98904.
Deprecate public API where appropriate and make it no-ops.
Remove all calls to it.
Get rid of the 'transition' css property.
For now, this means spinners don't animate anymore.
Instead of keeping a custom GPtrArray, keep it as a GtkCssArrayValue of
GtkCssStringValue. This way, we gain equality comparisons and print
functions for free.
All the properties now are a GtkCssArrayValue of GtkCssSadowValue.
GtkCssArrayValue already does everything we want, so no need to
duplicate its funtionality.
Only the ones that can be animated are marked of course. So more work is
needed.
This is important for
transition-property: all;
because it'll just animate all the properties that can be.
So instead of using
_gtk_css_style_property_get_id (GTK_CSS_STYLE_PROPERTY
(_gtk_style_property_lookup ("name")))
one can now use
GTK_CSS_PROPERTY_NAME
Esaier, eh?
Note: custom CSS properties still use the default GtkCssValue and always
will.
So there is a difference in css values used between those, even though
they both carry a GdkRGBA payload.
