A non-maximal arrangement of component tiles is reconfigured into a maximal arrangement.
For each identified active segment of a first span not having a matching active
segment in a second span, a maximal component tile having a width generally equal
to the width of the identified active segment of the first span and a height generally
equal to the distance separating the first and second spans is generated. The first
span is then modified by deleting the matching active segment of the first span
while adding each unmatched active segment of the second span. Maximal space tiles
are generated from inactive segments of the spans using a similar process. The
process is then repeated for each unselected span which fails to match the modified
first span.
