[luatex] Confirm change in TL 2016-pretest vs. TL 2015 behavior: dvilualatex fails because of pdfpageheight

[Scott Kostyshak]

Thanks for the quick reply, David.

So to make sure I understand, it is not expected that the example I sent
will compile successfully in the future (because it does not fall into
the situation you mentioned of "packages are updated to use the new
forms"). Did I get that right?

I looked at the manual and I see in 10.1 Primitives overlap that
\pdfpagewidth is an alias of \pagewidth. So I suppose the solution in
the example I gave is to just remove the following two lines:

\pdfpageheight\paperheight
\pdfpagewidth\paperwidth

If I remove those two lines will the behavior (imagine more complex
documents) be the same for newer luatex compared to using an older
luatex with those two lines included? Will it be the same as without
those two lines for older luatex (i.e. were those two lines always
useless)?

As you could probably guess, I don't know much about luatex. But LyX
exports LuaTeX so I'm trying to figure out exactly what we need to
change.

Thanks for your help on this,

Scott
