See http://www.cocoabuilder.com/archive/message/cocoa/2007/2/19/179016
"In 32-bit Cocoa, the limited precision of the IEEE float data type means that single PDF "point" accuracy is lost when views become taller or wider than 2097152 points. In other words, in a single view larger than ~29,000 inches tall, there will be drawing anomalies approximately equal to the size of a point due to inadequate numerical precision to represent individual points. Common approached to dealing with this uncommon problem include representing "pages" by views instead of representing an entire document by one view. Of course, this is only an issue if your document needs more than ~2,648 11 inch tall pages."
