[libvips](https://jcupitt.github.io/libvips/) is a pretty amazing replacement for IM/GM -- for the overlapping functionality, IM/GM still do some things vips doesn't, and vips will depending on how it was compiled in some functional paths call out to IM/GM as a dependency, too.

But for some tasks I was doing, I found that vips could accomplish the tasks I was doing in IM in up to an _order of magnitude_ less RAM _and_ CPU time. (GM was getting me more like 10% improvement at best).

It would be sweet if they'd add vips as a fuzzing target too.
