Sadly I cannot edit the wiki.

Is the wiki an appropriate place? We do need and "editor" (as in
person, not application) for this document and It seems Bill is doing
just fine ...

Anyway -- The layering issue is indeed important -- in gnuplot lines
are just drawn in the order they are requested -- last line on top. In
matlab, I think they are drawn in the order they are in the "children"
property -- can someone verify?
This is a VERY important issue. In octplot I use OpenGL (I think that
this is the case also for oplot and workshop). I am not sure that
layering is defined in OpenGL -- I was just about to ask on some
OpenGL list. Of course this could be circumvented by using z- offsets
in 2D graphs, which I already do in octplot, but it has to be difined
in this document!
