You don't "need" to have it in Chip these days due to the very nice C2P-routines available together with for example BlazeWCP which lets you keep you gfx in Fast. The scrolling can easily be extended to allow for 4-way scrolling in the same way one does a 2-way scroller.
This does require some more Fast-mem but i think that should not pose a problem today with almost every a1200 being expanded - correct me if you're still using a vanilla-machine :-)
