raymes@: I am hesitant to shift these two variables into
out_of_process_instance.cc and instance.cc, given we initialise
background_color_ to kBackgroundColor in pdfium_engine.cc.
Should we not initialise it at all and set it to kBackgroundColor should we fail
the isMaterial check in out_of_process_instance.cc?
