Re: Poster with layers

\setlayerframed is great - no need to define a layer for each piece of
content. That was new to me.
Now, to make sure that I have understood correctly by comparing code and
output:

>   [page]
>   [preset=lefttop]
>   [align=normal,
>    width=.25\paperwidth,
>    frame=off]
>   {\getbuffer}

This will be placed with its top left corner at the top left edge of the
page.

With the top right corner at the top right edge of the page, with an
offset (both x and y) of 0.2\paperwidth.

Centered on the page.

Ok. But it doesn't solve my problem. What I want to do is:
- Place X somewhere.
- Place Y with its top left corner 2cm below bottom center point of X.
	(Or some other reference point among tl, t , tr, l, c, r, bl, b, br.)

You see, I don't know exactly what goes into the layers and how big it
is, but I want to place someting else exactly beneath it.

Can this be done?
