Where does that 32768 number come from?

32768 = 2 ^ 15 is ofcourse the maximum signed short seems to be the maximum width/height on Chrome.
After more research I noticed this npm module updated today with good info! According to that we may reduce that to something like 16,384 for FF. Older versions of IE have lower limits.

Interesting. Thanks for the info!

I don't adding a dependency for this is worth it. I suggest finding the max of min values listed.

looks like 1 / 4096 will be good enough.

Thanks! Maybe you could put a comment above this line explaining where that 4096 comes from.

Lib.noneOrAll(containerIn.domain, containerOut.domain, dfltDomain);
