Usual practice is to use screen->Font->ta_YSize (screen->Font is a struct
TextAttr).
For instance,
WA_Top, screen->Font->ta_YSize + 3,
puts the window top 1 pixel below screen title bar.
(screen->Font->ta_YSize + x) * num,
figures the inner height necessary to display num lines with x spacing between
lines. If you use WA_Height to set, you'll also have to figure out the height
of upper and lower borders and that too.
