tikz picture is placed align left-upper corner

tikz picture is placed align left-upper corner

[Gao Ya'nan]

I draw a figure by tikz but found it is not in the middle but a little
left of the page, and then I wrote a piece code and impoved my view.

And I tried to add some parameters to put the figure in the middle but failed.

Thanks for any tips and test code is below.

\usemodule[tikz]
\usetikzlibrary[positioning, shapes, shadows, arrows]
\usetikzlibrary[backgrounds]

\starttext

\placefigure[here][fig:pci]{PCI System}{
\framed{
\hbox{
	\tikzstyle{abstract}=[rectangle, draw=black, rounded corners,
fill=blue!40, drop shadow, text=white, font=\small]
	\tikzstyle{cache}=[rectangle, draw=black, rounded corners,
fill=green, drop shadow, text=white, font=\small]

	\starttikzpicture[background rectangle/.style={draw=blue}, framed]
		\draw[help lines] (-5, -4) grid (5, 1);

		\node (Processor) [abstract, rectangle split, rectangle split parts=2]
			{
				{Processor}
				\nodepart{second}Cache
			};

		\node (AuxNode01) [below=of Processor] {};
		\node (Coherency) [cache, left=of AuxNode01]
			{
				{Cache Coherency}
			};
		\node (L2-Cache) [cache, right=of AuxNode01]
			{
				{Cache}
			};
	\stoptikzpicture
	}
	}
}
\stoptext

Does this

help.

Also, in TeX you have to be careful about trailing whitespaces. It is 
better to use

\framed{%

or

\framed
    {....

and the same for \hbox etc.
