DSPRES.DLL contains the core (always-installed) PM system fonts: System Proportional, System VIO, Helv, and WarpSans.
They are all raster fonts. However, I would classify DSPRES.DLL as a operating system file because it's one of the system DLLs. Also, the one in Hobbes font directory is only suitable as an update for Warp 3 systems, and IMO should be classified as a Warp 3 update/patch file.
