Hello.
After discussions with Richi, I decided to end up with the transformation and
thus
I would like to apply the original patch on top of what was done. Probably last
change
should be that we should renumber TDF_* values to start from 1 << 0 and holes
in numbering
should be eliminated?
Thanks,
Martin
