/*
	Set the values for selectors. Note that these values MUST be
	two bytes long and have the high byte be non-zero. The reason
	for this has to do with the way SysGremlins was originally
	declared. It took a GremlinsSelector enumerated value. Originally,
	there was only one value, and it was zero. The way the 68K compiler
	works, it decides that GremlinsSelectors are only one byte long,
	so a call to SysGremlins would push one byte onto the stack. Because
	all values on the stack need to be word-aligned, the processor
	subtracts 1 from the stack before pushing on the byte. Therefore,
	the stack looks like:

			previous contents
			garbage byte
			selector
			return address

	When the two middle bytes are read together as a word, they appear
	as: <selector> * 256 + <garbage byte>.

	With this setup, we have two choices: leave the selector size at
	one byte and limit ourselves to 256 functions, or define the selector
	to be a two byte value, with the first 256 values (all those with 0x00
	in the upper byte) to be GremlinIsOn. The latter sounds preferable, so
	we start the new selectors at 0x0100.
