This comes up every now and then, and while it seems that everyone thinks fill patterns would be nice to have, I suspect that every attempt to actually implement it have gotten killed in infancy.

The thing that is tricky to design right is the cross-device issues. Only some devices support this at all, and when they do, the patterns tend to be device dependent too. Probably not impossible -- there are other bits of the device drivers that deal with missing capabilities, like string rotation and clipping -- just, well, tricky.
