* "sonic mode" is autodetected, shadow/hilight is enabled by emulated game.
* AS is enabled by user and takes priority over "sonic mode".
*
* since renderer always draws line in 8bit mode, there are 2 spare bits:
* b \ mode: s/h as sonic
* 00 normal - -
* 01 shadow - pal index
* 10 hilight+op spr spr pal index
* 11 shadow +op spr - pal index
*
* not handled properly:
* - hilight op on shadow tile
* - AS + s/h (s/h sprite flag interferes with and cleared by AS code)
