o Added support for "global" device options to fall back on if no set
  for the device type queried, e.g. devOptions("*", pointsize=14) and
  devOptions("quartz", global=TRUE)$pointsize.

STATUS: Can currently get, set and reset global options.
TODO: Add option inherits=TRUE to enable falling back to global
      options in case the option is not set for the requested device
      type.
BUG FIX: Now devOptions() can set values to NULL
Version: 2.11.3 [2014-09-12]
o BUG FIX: devOptions(type, name=NULL) did not assign the option NULL.
o BUG FIX: On Windows, devOptions() assumed that the 'grDevices'
  package was attached.
Clarified
o Added getDevOption().
The default argument values for toNNN() are now clear again.

Forgot to export getDevOption()
Updated vignettes and tests to use devOptions("*") instead of old-style R
options.
Merging v2.11.4 from the master branch.
o CLEANUP: Dropped argument 'field' for toNnn(), because the default
  is now NULL which corresponds to returning a DevEvalProduct object.
  In turn, this object has the pathname as it's value, which was the
  previous default 'field' value.  Also, as.character() on this object
  returns the (relative) pathname.
o BUG FIX: Now getPathname(..., relative=FALSE) returns the
  absolute pathname.
Moved getPathname() bug fix to v2.11.4
o Added favicon() device, which is a wrapper for png() with bells
  and whistles.  It has its own device options.  Updated toFavicon()
  to use default argument field="htmlscript", which generates an
  HTML script that dynamically sets the favicon.
o Wrong \value{} description.
