Something like the following (ECMAScript) might help:
var iCTM = (document.documentElement.getScreenCTM()).inverse();
var newMatrix = document.documentElement.createSVGTransformFromMatrix(iCTM);
var targetElement = document.getElementById("YourElementID");
targetElement.transform.baseVal.initialize(newMatrix);
It can be used in your "reset" button or similar, or simply attached
to UA events such as zoom, resize, etc. in order to create the
illusion of elements which do not resize. :-)
This should work in current SVG implementations (Batik, Firefox,
Opera, Webkit). I believe ASV and possibly other implementations
require additional trickery in order to work.
Also, it should be fairly easy to adapt this to Java environment. ;-)
Comments and other possible solutions are naturally welcome. :-)
Hope this helps,
Helder Magalhães
