bug 1189846 - Print Edit 15.10 - found some issues during testing with progress listeners, now resolved.
bug 1258609 - Crash while printing via parent with pdf.js , about:memory shows large heap unclassified - problem is because canvases use a similar surface and create a new DrawTarget. Changed to use a similar DrawTarget. Up for review.
