Now onto step two: how can I typeset each glyph in the formula individually
such that it appears precisely in the right location?
I must be misreading something here, but I cannot figure out what
'the right location' means.
Since textext() always returns a single picture that can't be
glyph.

so, if in mkiv you want pieces, you need to textext each snippet that you
want as such
Alright... in that case how would I make sure that all glyph positions are
kept if my TeX material is, say, some complex formula? How could I find the
baseline with textext?

the fact that you have pieces in mkii is a side effect of dvitomp turning dvi

Hi,
Is anyone using tex i.e. not pdfetex/aleph/xetex? I'd likt to go etex

Hi Hans,
I only use aleph and pdfetex. I am concerned however, because aleph uses an
older version of etex, and so there may be unintended consequences
