48957: Set Pixel Adjustments
Used by the routines at HandleLandMine, HandleRemoteControlRobot, HandleRemoteControlBlock, HandleRemoteControlArrow, HandleBlockMovingEastWest, HandleConveyorNorth, HandleCollapsingBlock, HandleDeadlyObject, HandleFallingBlock, HandleFatBottomBlock, HandleRisingBlock and HandleMovingBlock.
Sets how many pixels the sprite of an object is moved, in x and y, from the position that CalculatePixelCoordinates works out. The isometric formula finds a corner of the object; these offsets sit the graphic on that box. There is an entry point for each pair of offsets, and the one that is used depends on the sprite. L is the offset in x and H is the offset in y. A plain block (object 30) and the wall parts (objects 13 to 15) have no other work, so their update routine is one of these entries.
