inconsistent handling of alignment

So I've been going through the shoes layout algorithms trying to figure
out how everything is supposed to work.  Another one of the things I hit
recently is that alignment works really weird within flows.  For
example:

 Shoes.app :width => 50, :height => 50 do
  flow do
    para "This is a test.", :align => 'center'
    para "And yet again."
  end
 end

Try resizing the window and watch the weirdness happen.

My feeling is that alignment should only be honored for children of
stacks, and that flows should have an align style that applies to
everything in the flow.

Thoughts?

Hi mental and folks,

Yeah, it looks weird at first. But after some trying.
I became to think that it might be not so weird.

I tried the below code. Look at a tiny online demo.

http://www.rin-shun.com/shoes/alignment_flow.swf.html

Shoes.app do
  flow do
    para "This is a %stest." % ("test " * 20)
    para "And yet again.", :align => 'center'
  end
end

The Shoes manual says:
- Once the end of the page is reached, the flow starts
  a new line of elements.

It seems to follow this rule, regardless of setting `center` option.
I'm not sure, though...

Well... it isn't weird in the sense that I understand why it's
happening.  I'm just not sure that it is useful behavior.

Sounds good. Seems like what one would expect, especially with Shoes
claiming to be web-like.
