[Tikzdevice-bugs] Peformance

[Cameron Bracken]

I would have been surprised if there were not issues on windows.  We
developed the tests for use in development (hence the reason they are
in inst/tests and not the standard tests/ location) and so did not
really have cross platform compatibility in mind. Good to know the
tests run successfully on windows.

The reference to /dev/null is just there to suppress the output of the
packages on loading and so does not affect the test at all. A similar
way would be

sink(tempfile())
<load packages>
sink()
