Ok, my apologies for not specifically writing what I'm looking for.

My point is that with

  \begin{pspicture}[](0,-2)(3,3)

it is significantly easier to adjust the depth of the pspicture when
incrementally filling it with content: there is no need to change two places or
to define a new length for each picture or to do whatever.

So the actual question is whether the new version still provides a way to
say "please, pspicture, put the baseline through the origin" instead of
saying "put it at -2 (which happens to be the current depth, I just looked
it up)".
