Map questions can now be on the world's countries besides Japan's
prefectures: a new question chooses its map above it.

The world is Natural Earth's 1:50m countries (public domain), as they are
on the ground, one region per ISO 3166-1 code (239; Gibraltar and the US
Outlying Islands from the 1:10m layer, which has them), named in every
language a studyset can be in from the Unicode CLDR (Unicode License v3,
its notice in the licence list). tool/maps/world_countries.py builds it;
the outline code it shares with the Japan script moved to outlines.py,
which still writes Japan's file byte for byte. The 1.8 MB file is parsed
off the screen's isolate.

Picking goes in layers on both maps: on the whole map one taps a group
(a continent, or Kantō, Kansai …; chips name them too) and the map flies
there, then one taps the region; Back returns. A group of one (Hokkaidō,
Okinawa) and what is in none (Antarctica) are picked at once. A country
in two groups (Russia, Türkiye, Cyprus) opens the one nearer the tap.
Oceania's frame runs past 180° so the Pacific stays in one piece.

What is still too small to hit gets a ring, 48 dp of reach as Material's
touch target: on the ring it is picked; near it, where the tap could mean
it or its neighbours, the map zooms in rather than guess. Pinching and a
mouse's wheel zoom as before.

Names show in the app's language, beside them the map's own (Japanese for
Japan) or the studyset's (キプロス beside Cyprus in a Japanese studyset).
