Hi,

I've been having some problems with tikz figures. When I define a new
tikz figure, I normally put it in a buffer:

\startbuffer[mypic]
	\starttikzfigure
		...
	\stoptikzfigure
\stopbuffer

which I use later when I place the figure

\placefigure{My picture}{\getbuffer[mypic]}

The problem is that the figure is not centred: it is always aligned with
the left side of the document. I guess this has something to do with
Context not being able to get the image bounds, since it works fine for
tikz images that are already precompiled into PDFs:

\placefigure{My picture}{\externalimage[mypic.pdf]}

Minimal example is attached.

Michael.
