I have two problems with figures placed into the left or right margin.
When the figure is in a group, extra whitespace is inserted between the
paragraphs that precede and follow the placefigure command. This happens
for figures placed by startplacefigure/stopplacefigure and tradiitonal
placefigure commands, and paragraphs placed by
startparagraph/stopparagraph or marked by par or newlines.
When the figure is not in a group, whitespace called for by
\setupwhitespace is lost, except when the paragraphs are marked by
traditional means. That is, whitespace is lost when
startparagraph/stopparagraph is used.
Interestingly, when that is changed to bpar/epar, the problem for
ungrouped figures disappears, but as I understand it, bpar/epar is not a
real substitute for startparagraph/stopparagraph.
There is probably a simple explanation, but it eludes me. I prefer to be
able to use startparagraph/stopparagraph, and it is sometimes desirable
to place a figure into a group in order to prevent unique settings from
leaking out.
The following should demonstrate the problem. Turning on grid setting
makes it worse. I get the same result with current betas and older versions.
\useMPlibrary [dum]
%\showgrid
\setuplayout [%grid=yes,
backspace=151pt,leftmargin=117pt]
\setupwhitespace[big]

you can test with this in cont-new.mkiv

Thank you, Hans. That works well, both on the example and on a more
complex real document.
