Dear list,
I have the following graphic
\startuseMPgraphic{TitleGraphic}
draw outlinetext.b (\MPstring{TitleText})
    (withcolor "titlefg")
    (withcolor "titleoutline");
\stopuseMPgraphic
which I tried to use as follows to produce a stylized 'title' head:
\setupMPtext{TitleText}{%
\starteffect[stretch]\bfc\namedstructurevariable{title}{title}\stopeffect}
\useMPgraphic{TitleGraphic}
[colors "titlefg" and "titleoutline" are set using \definecolor]
But, the 'stretch' effect caused by \starteffect[stretch]…\stopeffect does
not work with 'outlinetext' method in the MPgraphic. I have verified that
the desired effect is produced using 'textext' method instead. But in that
case I have to cheat (i.e draw twice; once with blownup) to get the text
outline.
Now, if I write instead
\setupMPtext{TitleText}{%
\kerncharacters[0.15]\bfc\namedstructurevariable{title}{title}}
\useMPgraphic{TitleGraphic}
then the desired effect is produced. As such, my purpose is served well by
using \kerncharacters.
Nonetheless, I request your kind help in understanding why this is happening
and/or if I am doing something wrong.
Thanks,

Please read '\setupMPtext' as '\setMPtext' in the above. Apologies for the 
typos.
