Add section about diagonal rules
See the corresponding thread on the list: [http://www.ntg.nl/pipermail/ntg-context/2011/058549.html rules with different thickness]
== Diagonal rules ==
Sometimes a diagonal rule is required in the top left corner cell of a table to create two fields, one for the left column and one for the top row.
<context mode="mkiv" source="yes" text="Gives:">
\startuseMPgraphic{DiagonalRule}
rulethickness := \frameddimension{rulethickness};
drawoptions(
withpen pencircle scaled rulethickness
withcolor \MPcolor{\framedparameter{framecolor}});
pair leftcorner, rightcorner;
leftcorner := (rulethickness, \overlayheight-rulethickness);
rightcorner := (\overlaywidth-rulethickness, rulethickness);
draw leftcorner -- rightcorner;
\stopuseMPgraphic
\defineoverlay

This solution has (at least) one caveat: Because the first
tabulate column is set in paragraph mode, it will eat up as much
space as <em>possible</em>, in contrast to occupying as much space as
</em>necessary</em>. That is why the width of the column has to be set
explicitly.
