Fixed a couple of variable/function definitions, as well as header handling to support 16K sequence coding at high bit-rates. The width and height are each specified by two bytes in the header. Use an extra byte to explicitly indicate the scaling factors in both directions, each ranging from 0 to 15. Tested coding up to 16400x16400 dimension.
