SimpleText file types

[BarnacleGrim]

I opened the BNDL resource in SimpleText. There are a few types there that I have never encountered before. Does anyone know what the tjob, qjob, sjob and rjob types do? I imagine they have something to do with graphics and printing.

Looks like something relating to QuickDraw 3D to me.

By the way, am I the only one here who finds it amusing that there is a file type called "sjob"?

bjob would be funnier...
