Improved comments on Saxman decoder in sound driver. Split Vscroll_Factor and Vscroll_Factor_P2 into their
FG and BG components and made use of them throughout the disassembly. Renamed sub_E98 to Do_ControllerPal.
Renamed loc_3A68A to SegaScr_VInt. Renamed some routines used in collision with terrain. Renamed Floor_ChkTile
to Find_Tile, which is what it does. Changed uses of ColArray+$1000 to ColArray2. Several object IDs were
fixed to use their correct constants. HTZ boss is a multi-sprite, so its offsets now use the multi-sprite
constants. Entries in AnimPatMaps always aligned the animated tiles to the end of block RAM, so a macro
has been defined to do that automatically.
