/*
Effect: Move and show the various components of the graph to
fill the size (xWidth x yHeight). Take into account
whether the user wants to show the legend or status
bars. Also take into account if we have room for these
items.
Internals: If the user doesn't want the status or legend windows,
they aren't shown. Also, if the user wanted the status
window but not the legend window, the status window is
not shown.
We may disregard the user's desire for the legend or
status bar if there is not room. In particular, a legend
window has a minimum width (LegendMinWidth ()) and a
minimum height (LegendMinHeight ()). These values are
fixed for a given session of perfmon. It also has a
preferred height, which takes into consideration the
size of the graph window and the number of items in
the legend. This value is returned by LegendHeight().
We don't show the legend if its minimum height would
take up more than half the graph height.
If we feel we don't have room for the legend, we don't
show the status window either.
See Also: LegendMinWidth, LegendMinHeight, LegendHeight,
ValuebarHeight.
Called By: OnSize, any other function that may remove or add one
of the graph components.
