OK, it appears cgLayout will not work with a resizeable Coyote Graphics
window at the moment. The reason is complicated, but it has to do with
the fact that users can't draw directly into a resizeable graphics
window. The window actually "hides" its identity so the user can't do
this accidentally. You have to "add" a command to the window.

At the time the command is "executed", the window reveals its identity
and allows you to draw into it. Since cgLayout has not been added to the
window (it can't be), it has no access to the window information in the
resizeable graphics window to calculate positions correctly.

Since it has no access (it sees the current window index number as -1),
it used the default window size to calculate the plot positions. This,
obviously, will be wrong in this case, since the default position is
640x512 and the window you want is 900x1200. This is why you are not
getting what you expect.

It is possible I might yet discover a way to give cgLayout access to a
hidden cgWindow, but I have other things to do today and can no longer
work on this. The workaround, of course, is to simply use a regular
IDL window (cgDisplay). This will give you device independence, since
cgDisplay works the "same" in PostScript.

Cheers,

David
