Sorry for the delay. BT/ET (begin/end text object, see PDF specs) is something I took over from the PDF renderer. The idea behind it is to make the PS renderer as similar to the PDF renderer as possible so it's easy to use a differ to identify code that could be factored out from the two renderers. I've already identified a few candidate snippets.
I'm sorry if this confused you. But you're right, the code doesn't do much more than moving to (0,0). The code for BT/ET is inspired (but simplified) by the PostScript code generated by AcrobatReader when converting a PDF to PostScript. Acrobat Reader pretty much emulates the PDF vocabulary in PostScript. By my doing the same I can make the code of the PS renderer very similar to the PDF renderer for the reason above. Concerning your last question: I haven't yet paid close attention to the efficiency of the code produced. I just wanted to get it running so you could continue. The matrix manipulations could probably be simplified. I hope this helps. Anyway, I'm back and ready to help you. If you have something running, even if it's not the final version, you can wrap up a diff file and I'm going to apply it. Any luck yet with getting CVS running?
