The 0 0 creates a matrix that has a scale and a shear of 0. That's 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 that is fatal. The error will still be posted, now with an extra
detail.
