blanks with glue in mkiv

[Aditya Mahajan]

Hi,

Blanks with glue do not work with MkIV. For example,

\defineblank[test][3pt plus 1pt minus 1pt]

\starttext
some text
\blank[test]
some text
\stoptext

gives

The old commands to define own blank values do not work in MkIV, the old 
MkII commands are mapped to the new ones but MkII and MkIV expect 
different settings for them.

The old \defineblank command is replaced by \definevspacing which allows 
only keywords (penalty, category and order) with a value (e.g. 
\definevspacing[\v!samepage][penalty:10000]), you can also define 
synonyms (\definevspacing[\s!default][\v!white]).

The \defineblankmethod command is replaced by \definevspacingamount but 
both use a different syntax, while the old one expected the value in 
curly braces the new command wants them in brackets. This is also the 
command you can use because ot allows TeX skip values but it expects 
two, one for grid typesetting and another one for non grid text, e.g.

   \definevspacingmethod[test][3pt plus 1pt minus 1pt][3pt plus 1pt 
minus 1pt]
