• bug 1156742 - print to xps with low integrity sandbox - fonts are really hard - fixed various problems found in testing:
  • memory corruption from the way I was pulling out names from TrueType files
  • timeout due to misunderstanding the way nsPagePrintTimer works
  • added a load of null checking to the Moz2D event playback code, as it currently just expects everything to be fine
  • added a new patch to only send the font data once and cache on the parent, scaled font then reference that
  • just found issue with TrueType font collections for GDI fonts, working on fixing that now
