 == Notes on row spanning ==
 
-'''''TBD'''''
+Layout for a cell spanning in row direction has to be started on the first row it \
occupies. The idea to defer layout to the last row occupied by a cell won't work \
since in the mean-time a page might be full and some of the content may already be \
needed on that page. That means that for collapsing border model the start and end \
borders for each grid unit have to be determined prior to starting layout \
(getNextBreakPoss) in the first row occupied by a cell. Each grid unit may have its \
own border and the widest of the border segments determines the left and right indent \
for the content rect. This makes it necessary to do a prefetching of rows in the body \
LM. For each of the prefetched rows the grid units are set up and the start and end \
border segments of each grid unit determined. The before and after border segments \
are later determined (and sometimes redetermined) during layout because these borders \
may depend on break decisions.
