* Basically, initialisers go in the constructor arguments, and things for setting format go in set_format. * Initialisation patterns can be specified with an enum discriminator or with a FUNC and optionally a tag. * Formats can be specified with an enum discriminator or a size and function pointer. * You must always supply the number of entries when setting the format. * When initislising with a paletter initialisation member, you can specify the entries and indirecte entries together. * The palette_device now has a standard constructor, so use .set_entries if you are specifying entry count with no format/initialisation. * Also killed an overload on delegates that wasn't being useful.
