R devel - Nov 2016 - getGraphicsEvent() alternative for cairo graphics device?

Hi

The current status is that I am keen for people to contribute some 
testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951)

There were also some getGraphicsEvent() changes/fixes suggested by 
Richard Bodewits (cc'ed), for which I am also seeking test code.

Hi Paul,

Thank you, for some reason I didn't seem to get an email notification
for your bugzilla comment!

I will try to send you something shortly.

Hi Paul,

Thanks for your efforts. Do you have an idea when my patch(es) might
be committed? Is there anything I can do to help move this along?

Thanks,

Hi

Just taking a bit more of a look at this today (currently fixated on 
making sure I can build some good regression tests).

The best thing you can do is to keep reminding me like this :)
