    CSS provider: Add a way to emit errors · 2c7fdf64
    Matthias Clasen authored
    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).
