IF XML
When using multiple threads to render the attached IF XML to PCL using the
Painter the following exception occurs. The exception does not occur when only
a single thread is used. In a quick debugging session we observed that when the
error occurs the method PCLPainter.getTextBoundingBox returns a rectangle with
negative width
