grid is slate grey using SumatraPDF on Windows, so I think the problem 
is not unique to Adobe Reader on Windows.  It may be that the solution 
actually leverages a problem in evince on Linux? Or depends on something 
that isn't quite nailed down in the standard?

My understanding is that SumatraPDF uses a different rendering engine 
than Adobe Reader... (the application is certainly way faster)... likely 
evince does too (since it produces different results). Somewhere I read 
there are only about 3 PDF rendering engines, so maybe this covers the 
gamut, or maybe there is a 4th...
