animateTransform rotate, with cx/cy is broken I expect that this has to do with SVGTransform having "lossy" storage for cx/cy values in a rotation. Once they're applied to a transform matrix, they're difficult (if not impossible) to correctly extract. Either we'll need to add floats to store cx/cy in SVGTransform, or we'll have to use a different class (like SVGTransformDistance) when needing to store these values.
A fix for this was landed in r19201.
This functionality has broken in the nightly build as of at least 2007-01-30... should be reopened. this is another assertion failing
Reopening per Comment #2. Charles, please provide some more information (which tests, output when failed). Thanks!
Closing the bug. There are not issues with this functionality. At least not with our tests.
