Format description

Early CorelDraw files are of an undocumented proprietary format where the first two bytes spell WL in ASCII. Later formats were based on RIFF, with RIFF as the first four bytes and a version identifier in bytes 9 to 15. The inner details (the data chunk of the RIFF version) remain proprietary.
