/*
* GSAutoLayoutStandardManager objects are layout managers which
* layout segments one after the other. Some segments are expanded,
* other segments are not expanded. The standard autolayout manager
* guarantees that whenever there is a resize, all segments with
* expand = YES are expanded, and that no segments with expand = NO
* are expanded unless there is a sound reason to do so. This
* autolayout manager aligns segments in different lines, so that
* segment 0 of one line is the same size of segment 0 of all other
* lines. By default, all 'span' attributes of all segments should be
* 1. If a 'span' attribute of a segment is different from 1, it is
* interpreted as the number of line parts (columns if we are laying
* out horizontally) that the segment takes up.

* The minimum layout is determined by

* - finding how many line parts we have.

* - compute the length of each line part, which is the maximum length
* of all segments contained in each line part (ignoring the special
* case of segments with span != 1 for now), and whether each line
* part expands or not (it expands if any of the segments displayed in
* it expands).
*
* - for each segment which has a span != 1, if the sum of the length
* of line parts it spans is less than the minimum size of the
* segment, then enlarge all those line parts so that their sum get to
* this minimum length (only enlarge line parts with expand = YES and
* all of the same amount; if there is none with expand = YES, expand
* all of an equal amount); if the segment has expand = YES and no
* line prt it spans is already marked as expand = YES, then mark them
* all as expand = YES.
*
* - layout each line by laying out all segments in a line part to be
* as big as that line part, and segments spanning multiple line parts
* to be as big as the sum of those line parts. All segments are one
* after the other one.
*
* - the biggest line length is the line length.
*
* - layout the segment contents inside each segment according to the
* border for that segment, and the alignment of the segment contents.
