Subject:     allowShellResize affects window size only w/ Lesstif with XmNx/y set.

I have found the X parameter allowShellResize seems to allow Lesstif to
make the window as big as it would like to fit all the child widgets
even if XmNx and XmXy are set.  However, it states in the Motif man
page for XmDialogShell: "For the managed child of a DialogShell,
regardless of the value of the shell's XmNallowShellResize resource,
setting XmNx or XmNy sets the corresponding resource of the parent..."

I've included a modified BulletinBoard test1 (maybe a new test14?)
that demos the problem.  Under Motif 1.2 and 2.1 this window will show
up as 200x200, but with the lesstif-current it is 359x342.

	Thanks,
	Rick Niles.
