Hypothetically, a subclass of SourceEditorView might want to store metadata in a hidden header area of the file. Overriding ProcessLoadText gives the subclass an opportunity to extract said metadata, and ensure that the text loaded into the Document excludes it. Similarly, ProcessSaveText would allow this subclass to inject updated metadata into the file text just before the write occurs.
