Hallo,
for text positioning in a layer I needed alignment to baseline. I do not
known if I missed something but I did not find it in the current
ConTeXt. So I did that. Baseline is choosen by capital 'B' in the
position parameter. ('B' is adopted from grahicx LaTeX/plain package.)
Also I add \ctop, \ltop, and \rtop in sence of \cbox, \lbox, and rbox,
respectively.
I suggest to add the macros to core-box and supp-box.
