/*
* Main constrained layout algorithm. Look at all the child
* windows, and their constraints (if any).
* The idea is to keep iterating through the constraints
* until all left, right, bottom and top edges, and widths and heights,
* are known (or no change occurs and we've failed to resolve all
* constraints).
*
* If the user has not specified a dimension or edge, it will be
* be calculated from the other known values. E.g. If we know
* the right hand edge and the left hand edge, we now know the width.
* The snag here is that this means we must specify absolute dimensions
* twice (in constructor and in constraint), if we wish to use the
* constraint notation to just set the position, for example.
* Otherwise, if we only set ONE edge and no dimension, it would never
* find the other edge.
*
* Algorithm:
Mark all constraints as not done.
iterations = 0;
until no change or iterations >= max iterations
For each child:
{
Calculate all constraints
}
iterations ++;
For each child
Set each calculated position and size
