/*

* The renderer has 4 modes now:
|
||||
* - normal
|
||||
* - shadow/hilight (s/h)
|
||||
* - "sonic mode" for midline palette changes
|
||||
* - accurate sprites (AS)
|
||||
*
|
||||
* AS and s/h both use upper bits for both priority and shadow/hilight flags.
|
||||
* "sonic mode" is autodetected, shadow/hilight is enabled by emulated game.
|
||||
* AS is enabled by user and takes priority over "sonic mode".
