that is really needed in LMTX. In most cases, metapost processing does not have
a significant processing delay.
if images are the same one can use the reuseMPgraphic or uniqueMPgraphic
features .. plenty of examples can be found, but as Aditya poined out mp
is quite fast (but reuse saves on file

Hans, is this a bug? Has something changed?
I don't know .. no example
I provided an example in
http://www.ntg.nl/pipermail/ntg-context/2013/071552.html
However, it seems to be fixed in a recent beta. At least it works

everytime used.
