Hi,
linear shading in MP does not work with xetex. Consider
\setupcolors[state=start]
\starttext
\startMPcode
path p ; p := unitsquare xyscaled (5cm,5cm) ;
linear_shade(p,1,red, blue) ;
\stopMPcode
\stoptext
This runs fine with pdftex and luatex, but with xetex I get
! Undefined control sequence.
\@MPSK@@MPSK@30 ->\startMPshading
{14}\setMPshadingcolors
{4}{5}{6}{9}{10}{1...
\handleMPspecialcommand ... \MPspecial \endcsname
\fi \ifcase

\donetrue
\doresetMPstack ...
l.20 ...1 1 0 0 0 0 0 0 1 141.73225 141.73225 1 30
It is more than simply supp-mpe not being loaded. If I add
\input supp-mpe, then I get
[MP to PDF] (./test-mpgraph.1
! Undefined control sequence.
\MP special 30 ...6}{9}{10}{11}\immediate \pdfobj

Thanks,
Aditya

Since no one replied am I correct in assuming that this is currently not
possible or requires a lot of work?

My guess is that there are communication problems with the pdf
backend (dvipdfmx). In XeTeX, that communication has to happen
via \specials. It could be impossible, or it could simply be
that Hans doesn't know what \special to output.
Best wishes,
Taco

it's just that i didn't adapt some spec-dpx code when i went from
supp-pdf+supp-mpe to meta-pdf
