# draw a single item. (There are multiple entries when
# [Show All Items Below Here] is in effect.)
# $itemboxes->[i] is a ref to a hash.
# $itemboxes->[i]->{'item'} is the FAQ::OMatic::Item object that this
# itembox represents.
# $itemboxes->[i]->{'rows'} is a ref to an array, each element of which
# is a row, structured as described below. Each row corresponds
# to a part in the item, plus a few extra rows for other parts of
# the page.
# $itemboxes->[i]->{'rows'}->[p] is a ref to a hash, describing that part.
# $itemboxes->[i]->{'rows'}->[p]->{'type'} is one of
# 'three', 'multirow', 'wide'.
# $itemboxes->[i]->{'rows'}->[p]->{'id'} is a debugging string that
# indicates the source of the row data
# type 'three' parts have ->{'body'}, ->{'editbody'}, ->{'afterbody'}
# refs. 'body' is a hash ref to 'text' and 'color'.
# 'editbody' is an array ref to edit cmds that apply to this part body.
# each element of the array is a hash of 'text' and 'color'.
# 'afterbody' is an array ref to edit cmds that apply after this
# part body.
# type 'multirow' fields have ->{'cells'}, a ref to an array of cells
# that should be laid out horizontally.
# type 'wide' fields have ->{'text'} and ->{'color'} parts that should
# fill the width of the display.
