These were Espi's second set of STAR* textures that he made for
Freedoom, and he ultimately replaced them with the ones that we have
now. However, I always liked these textures and the fact that they have
a very different and distinctive look compared to the original Doom
STAR* textures.
While this doesn't roll back STAR* to using these textures (and I don't
think we should), it adds them back as a second set of textures under a
different name (s/STAR/ESPI/). It would be nice if some of the Freedoom
maps end up making use of these in places and a nice tribute to Espi who
contributed so much to Freedoom in its early years.
