// The Apple //e card does not implement double lores correctly.  The colours
// used on the aux bank need to be shifted but the //e card expects unshifted
// colour values (ie the same as those on the main.  This function is called
// when the game detects it is not running on a //c or //gs.  I would like to
// get_ostype() from the cc65 runtime but it doesn't work reliably for detecting
// the //e card.  So I put in my own detection based on the technote.  If the
// function detects it is runing on a //e card, it causes the graphics
// routines to use the same colours in the main and aux banks.
