it looks like we fail this one for similar reasons:

It really can't be that hard to add.  Unfortunately right now JSSVGPoint is a custom binding.  Not that that will make it any harder to add... it will just make it harder to add to both Obj-C and JS.

Here is another testcase, simpler than the slider example:

Bug report 11734, adresses the missing SVGPoint.matrixTransform() function while fixing other problems with SVGRect/SVGPoint/SVGNumber JavaScript wrappers. Marking as duplicates.

Andreas testcase SVGPoint_test.svg shows a problem related to getScreenCTM() & viewBox, as Rob found out - not closing the bug yet, this has to be resolved into a new layout test & fixed.
