-TODO:
- - Non shrink-to-fit row-col behaviour.
- - Give justification styles, so can e.g. centre
- the rows & cols, distribute the available space...
- - Shrink-to-fit: should resize outer window (e.g. dialog box)
- if directly associated with this kind of window.
- - How to deal with a rowcol that stretches in one direction
- but shrinks-to-fit in other. E.g. a horizontal toolbar: the width
- stretches to fit the frame, but the height is constant
- or wraps around contents. The algorithm currently assumes
- both dimensions have the same behaviour. Could assume a constant
- height (absolute value).
- - rowcol where each row or column is aligned (length of
- largest element determines spacing)
- - Groupbox sizer
- - Analyze aesthetic dialog boxes and implement using sizers.
- - What reuseable components can we provide? E.g. Ok/Cancel/Help
- group of buttons.
- - use wxStaticItems for aesthetic dialogs.

- * 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.
-

- until no change or iterations >= max iterations
- For each child:
- {
- Calculate all constraints
- }
