This logic is odd given that enable_printing sounds like a boolean.  Do you know
the domain of values for enable_printing? Can we explain why "== 1" translates
to "enable_full_printing"?

Yeah, I've been wanting to rename it. Currently it matches the GYP exactly.
Another case like this I renamed to foo_mode. I still plan to get to it, but I
will have to update all the files that reference it so it's not super trivial.

The reason that =1 means "full" is that it used to be 0/1 like everything else,
and then the Android people came by and hacked on a partial mode and 0 and 1
were taken, so they used 2. Yes, this is very sad.

I almost want the ability to take an array of strings, check for the
corresponding boolean, and then add them into another array. Sounds too
complicated for the GN language though. :-/
