[dev-context] recent failure in mp graphics or clipping

Hello Hans,

I would need to create a minimal example, but I cannot do that before
I get the module to work again (\savebuffer) and I need to finish the
report first (before getting lost in bug reports instead of
concentrating on content).

When compiling one month old document with mkiv I stumble upon the
following problem. I had to run mkii to generate external files first
(via buffers) and then I tried to run mkiv and I get the following
error report. If it rings any bell to you, feel free to fix it and I
will gladly test it. (Which command exactly is undefined? \ifcsnameMPC
can indeed only be found at a single place, most probably undefined
indeed. I'm using clipping on PNG graphics if that helps.) Else I will
come back to it once I'm finished with the report. (I'm still using
mkii anyway, so there's no particular hurry.)
