You don't switch layout to fullpage!

Here is a complete working example:

\unprotect
\setuplayout
   [\c!location=\v!middle,
    \c!style=\ss,
    \c!backspace=2.5cm,
    \c!topspace=1.5cm,
    \c!width=16cm,
    \c!margindistance=.25cm,
    \c!margin=2.5cm,
    \c!height=\v!middle]

\definelayout
   [fullpage]
   [\c!backspace=0pt,
    \c!topspace=0pt,
    \c!width=\v!middle,
    \c!height=\v!middle,
    \c!header=0pt,
    \c!footer=0pt]
\protect

\definepapersize[main][A4][A4]
\definepapersize[diagram][A4,landscape][A4,landscape]

\starttext

And the actual image in my component is here:

\page 
\setuppapersize[diagram]
\setuplayout[fullpage]
\placefigure
     [force][figure:MyImage]
     {My image caption.}
     {\externalfigure[cow][factor=max]}

\page
\setuppapersize[main]
\setuplayout[reset]

The document is all in portrait mode, save the page with the figure
which is landscaped, as intended. But the image sits only occupying the
top left quarter of the page. I've tried changing factor from max to
broad and fit, and to no avail.

\stoptext

@Hans: Does it make sense to modify \adaptlayout so that it will also 
accept pre-defined layout. So that we could use:

     \page
     \adaptpapersize[diagram]
     \adaptlayout[fullpage]


Current, \adaptlayout only accepts key-values.
