Hi,
I started using 'MPinitialisation' to store some global variables. Much
easier than passing them over and over again to MP macros. Sadly this
way is inaccurate with the unit 'px' (no such problems with 'pt').
See attached example. The frame gives the exact size, showing that the
MP graphic is 'out of bounds'.

same result for both marks
