Currently, GtkCssProvider can emit ::parsing-error only during the actual parsing, although the documentation hints that it might happen at other times. This commit adds a emit_error method to the GtkStyleProviderPrivate interface that will let us emit errors from the compute() implementations as well, which can be useful (e.g. if an image fails to load).
