top layer / numbered layers?

top layer / numbered layers?

[Henning Hraban Ramm]

While I wait for a solution of the mtxrun error, another question:

I know how to use layers or overlays as backgrounds. How can I get a  
layer *above* the "normal" text plane?

say...

\definelayer[PageTop][x=0mm,y=0mm,width=\paperwidth,height= 
\paperheight,repeat=yes]
\setupforegrounds[page][background=PageTop]

\setlayer[PageTop][hoffset=10mm, voffset=10mm]{%
\externalfigure[koe][with=40mm]}

I just found that \framed knows "foreground=", but as far as I could  
find there's nothing like \setupforegrounds or \setuplayers.

An idea:

It would be nice if we just could use some number defining above or  
below main text like in:

\definelayer[PageTop][x=0mm,y=0mm,width=\paperwidth,height= 
\paperheight,repeat=yes,layer=1]

positive numbers would be above main text, layer=-1 would be below; 0  
is reserved for main text.
This way we could stack layers more easily, similar to z-index in CSS.
What do you think?

You can use the 'foreground' value:

\setup...[...,background={<behind the text>,foreground,<before the 
text>},...]
