css: Huge refactoring to avoid computing wrong values Here's the shortest description of the bug I can come up with: When computing values, we have 3 kinds of dependencies: (1) other properties ("currentColor" or em values) (2) inherited properties ("inherit") (3) generic things from the theme (@keyframes or @define-color) Previously, we passed the GtkStyleContext as an argument, because it provided these 3 things using: (1) _gtk_style_context_peek_property() (2) _gtk_style_context_peek_property(gtk_style_context_get_parent()) (3) context->priv->cascade However, this makes it impossible to lookup values other than the ones accessible via _gtk_style_context_peek_property(). And this is exactly what we are doing in gtk_style_context_update_cache(). So when the cache updates encountered case (1), they were looking up the values from the wrong style data. So this large patch essentially does nothing but replace the context argument in all compute functions with new arguments for the 3 cases above: (1) values (2) parent_values (3) provider We apparently have a lot of computing code.
