Emmanuele Bassi f4d8fb054a paint-node: Use JSON-GLib for debug serialization
Instead of our homegrown string building; this at least ensures that
we're generating proper data, instead of random strings. Plus, using
JsonNode and JsonBuilder, we can ask the PaintNode subclasses to
serialize themselves in a sensible way.
