Actually, the behavior you see is as it is documented by
Norm.  If you read further down the page of
http://www.docbook.org/tdg/en/html/imagedata.html
you will see a table indicating how scalefit defaults are determined.
If Viewport area is specified (width) but Content area is
not (contentwidth), then the scalefit default is 1.
That means it scales to fit the available viewport width.
It is done for backwards compatibility.

You want to set scalefit="0".
