/*
  Notes:
  - Reversed split option starts parting out from right [bottom].
  - Minimal partition of a split is 0 pixels.
  - Minimum width of horizontal splitter is determined by sum of
    all visible children's default widths, and height by maximum
    of all visible children's default heights; analogous for vertical
    splitter of course.
    [This can be done because the default width (height) does not depend
    on the widget's current user-specified actual width (height)].
  - For convenience, width/height of <=1 replaced by minimum width/height,
    but only if both width and height of child is <=1 at the same time.
  - Should we send SEL_CHANGED and SEL_COMMAND also when splitter arrangement
    was changed programmatically?  When bar size changed?
  - FXSplitter interprets layout hints on some of the children so that certain
    children have a minimum width (height) constraint on them.
    Note that this rule must have one exception: the last (or first if the option
    SPLITTER_REVERSED has been passed) must necessarily be allowed to be
    any size.
  - If we're just re-sizing a split, do we need to incur a GUI-Update?
  - Do we need to somehow insure that the sum of the sizes of all
    partitions never exceeds the size of the splitter itself?
  - Should we drop default parameters on 2nd constructor so as to
    prevent conflicts on compilers where NULL is defined as 0 instead
    of __null?
