The 0 0 creates a matrix that has a scale and a shear of 0. That can't be good.
I'm now using a default in case of error and the file renders (although not as
good as Adobe). The error you posted is non fatal, it is the NPE coming after
that was fatal. The error will still be posted, now with an extra detail.
