Mike Conley d3d99035d8 Bug 1145916 - [e10s] Defer starting a GTK Print Job during printer enumeration until the next tick. r=karlt
Before, we were calling nsDeviceContextSpecGTK::StartPrintJob within the
gtk_enumerate_printers callback function as soon as we found the printer
we wanted to print from. This was causing the GTK printing backend to get
confused about what the capabilities of the selected printer were when running
in the content process, due to https://bugzilla.gnome.org/show_bug.cgi?id=753041.
This moves the call to StartPrintJob to the next tick of the event loop.
