Hi,
I uploaded a new version of lmtx: a next step in this matrix and such
graphic part ... (also bTABLE done).
The matrix bit has a high level MP interface, also because it's a nice
example of implementing one (not much code needed actually).
Support in bTABLE .. eTABLE is kind of interesting as it separates the
ornamental part from the text part. The sxample only shows some simple
stuff. I'll probably also add this to the other table mechanisms. (Not
hard but I don't want to impact performance when it's not used.)
The
\startoverlayMPgraphic{mp:whatever-6}
is new and automatically defines the overlay so that saves some code.
\startMPoverlaydata
is just a collector that can be flushed in-line (which wilkl also reset
it).
All this is probably mostly useful in an educational setting. We'll see.
