When I use uniqueMPgraphics, things run faster, but I get errors and
warnings. They look like this:

The tex looks like:

\startMPinitializations
numeric FrameDist, Inner, Middle, Outer ;
FrameDist := 0.6;
Middle  := -0.2 ;
Inner := Middle - FrameDist;
Outer  := Middle + FrameDist;
\stopMPinitializations

\startuniqueMPgraphic{table:frame:lrtb} % all single
draw OverlayBox enlarged Middle ;
