(The characters in the gray fonts have to be a whole number of device pixels wide, and so the tfms are not device- or magnification-independent. Therefore, there is a check in gray.mf to ensure that mag=1. You should just leave out any reference to `mag' when running Metafont on a gray font like this.)
