Actually, that might be 3, since the points in the rect are inclusive (99 to
101 = 3)?

Because there has to be actual room to show the line itself. If you look at
the inspector palette after selecting a simple horizontal line, you'll see
the 'points' property is something like:
##
50,100
300,100
##
Now switch to the 'Size & Position' panel. You'll see that the 'rectangle'
of the graphic actually fits around the line:
##
49,99,301,101
##
Thus the 'minimum' height of the graphic is (101-99) = 2. My preferred methd
of updating a line graphic is setting the 'points' property, and letting the
engine update the 'rectangle' acordingly.
