    Enable the tile clear "optimization"
    
    Not really faster yet because we're using the float-valued put/get_tile()
    functions so we're doing quite a bit of float/int conversion.  That can
    be fixed though...

    Make sp_tile_cache_flush_clear() static.
    
    Also, misc clean-ups, comments.

    Convert the clearValue back to floats for sp_tile_cache_clear()
    
    It might be nice if sp->clear() took the color/value as floats...

    Some tile cache improvements, clean-ups.
    
    Code for optimized clears (per-tile flag indicating clear status) in place
    but not enabled yet.
