Hi Robin,

This gets me partially there.  I also need to take into account
f.getSpaceBefore and f.getSpaceAfter.  I ended up coming up with what's
mostly done in reportlab.platypus.frames._add().  But I forgot to take
into account that there shouldn't be space before it this is the first
item on a frame.  In my case, there won't be any but I stuck that logic
in there too. :-)

I created a list of styles for each of my recipe elements that shrink
more the further you are along the list.  That way I have control over
which page items shrink first to make space on the page.  It's pretty
darn neat and it seems to work pretty well. :-)

Thanks for the guidance!
