We did consider the idea of a hyperbolic lens early on, but dropped it
both because the scaling interfered with the idea of the zoom levels
and, more importantly, because we were informed that dynamic scaling
of the sprites simply isn't practical on the hardware.  It's a nice
approach for many applications, though.
