Hi Thomas,
I wanted to test the static path, available at
http://issues.apache.org/bugzilla/show_bug.cgi?id=36627 but I am
struggling to see any performance differences. Maybe I had problems
applying the patch or I used the attribute wrong.
First of all, I got error messages when applying the patch. I applied
the patch to the latest SVN version (fresh checkout). Here is the output
of my patch command:

It seems like some of the Hunks failed. Is that a problem?
--------------
assuming that the patch worked correctly (I am not sure about that), I
prepared an example:
http://www.carto.net/papers/svg/navigationTools2/index.svg where I
applied batik:static="true" to the <g> element with the id
"mainMapGroup" - a group that contains a raster image and a path
element. That content is not subject to change, at least not while
dragging this group (with a transform), or while drawing a manaul zoom
rectangle on that element.
The thing is, that on my system (SuSE Linux) I can't see any performance
differences while dragging the map content or drawing the zoom rectangle.
Is that not a suitable situation for the static attribute or did simply
the patching not work?
Thanks for any info on that topic,
Andreas
PS: I am now also testing on Windows, to see if there is any difference.
