too_big.i4.v = window_calc_top_row_c(top_row.i4.v, height.i4.v,

	This routine calculates the actual top row of screen coordinate
	for a window given a proposed top row location specification and
	the window's height.  The coordinate for the top row of the
	window can contain the defined constants WMNGR_CENTER to center
	the window.  These coordinates can also contain values created
	by the WINDOW_xxx_COORD macros which support special positioning
	options.  In addition, if part of the window would originally
	have been off screen, it will shift the window coordinates in
	order to place it entirely on the screen.  A value of TRUE will
	be returned if the window is too large to fit on the screen.
	Otherwise, a value of FALSE will be returned.

	top_row		top row of window (use WMNGR_CENTER for centering
			or WINDOW_xxx_COORD macros found in macro for
			other special positioning)
	height		height of the window including the borders
	real_top_row	returned actual top row of window

	This function returns status values as follows:

	TRUE			window is too large
	FALSE			window will fit

	This function requires the following include files:

	cnsparam_h, cbslib_h, macro_h
