This is a test. Eventually, if success is found, it’ll be merged into
#32059 and this PR will be closed. Please don’t merge it from this PR.

Part 2 of the Ipe test. Need to use this Lua to get a clean test that’s
actually useful to me.

The test bot doesn’t test the Tex requirement. Darn. The INSTALL
document in Ipe 7.1.5 has it down as a requirement, but I’ll have it
tested without just to check the Lua linking and the patch.

Test No.3. There’s definitely a TeX dependency in here somewhere, but
I’m going to see how far I can get without it to narrow down the rest
of the errors.
ipe: add 7.1.5 bottle.
lua: add 5.2.3_1 bottle.
