updateHeader (1 byte): An 8-bit, unsigned integer. The format of this field is the same as the updateHeader byte field, specified in the Fast-Path Update (section 2.2.9.1.2.1) structure. The updateCode bitfield (4 bits in size) MUST be set to FASTPATH_UPDATETYPE_PALETTE (2).

compressionFlags (1 byte): An 8-bit, unsigned integer. The format of this optional field (as well as the possible values) is the same as the compressionFlags field specified in the Fast-Path Update structure.

size (2 bytes): A 16-bit, unsigned integer. The format of this field (as well as the possible values) is the same as the size field specified in the Fast-Path Update structure.

paletteUpdateData (variable): Variable-length palette data. Both slow-path and fast-path utilize the same data format, a Palette Update Data (section 2.2.9.1.1.3.1.1.1) structure, to represent this information.
