[dev-context] itemgroupcolumns: page-mix.mkiv

Hi, can the direction setting be added to the itemgroup columns? \definemixedcolumns [\s!itemgroupcolumns] [\c!n=\itemgroupparameter\c!n, + \c!direction=\itemgroupparameter\c!direction, \c!separator=\v!none, \c!splitmethod=\v!none, \c!grid=\v!tolerant, \c!internalgrid=\v!halfline, % new, we may still revert to \v!line \c!balance=\v!yes] Wolfgang
