Yes. \scratchcounter is defined in syst-gen (IIRC). So are a bunch of
other temporary variables.

I can not really check the font stuff, since I do not have txfonts and
rsfs on this machine. But the matrix alignment appears to be working
fine. I am attaching the test for just the matrix alignment. When I get
home, I will try to see what goes wrong when you add other fonts.
