The new parasite format cannot be loaded by old versions of GIMP. This means we must bump the XCF version (even though technically we didn't really touch the XCF format itself because text layers are stored in a hackish way, yet text layers are just too important nowadays to not care). Nevertheless if an old XCF with text layers was loaded and the text layers left untouched, the old parasite will be saved back as-is. Therefore no need to bump the XCF version in this specific case. Only when we created new text layers or edited existing ones.
