I'm not certain about this line.  I don't know what visibility does but did
wonder if it might imply adding itself as a target for builds that don't want it
and might fail with it.

I'm also not sure about the rest of this file.  I just copied all the lines that
looked appropriate from the unit test above based on what I could see in the old
.gyp file.  It does build and run on Linux and Chromium, though.
