Question 1:

Suppose
	Glyph* in = ...;
	y is Dimension, and size is Coord.
	FixedSpan* out = new FixedSpan( in, y, size);

If the natural size of "in" is smaller than the "size" specified,
is "in" always lay in the middle of "out"?
How can I make "in" align to the top of the fixedspan?

Question 2:

Why is it the append of a LRBox to a FixedSpan only shown once (refer
to the h1 and h2 below)?  How can I make it display everything appended?

Thanks in advance.
