-- Driver: shoots the launcher's Touch Controls editor with the built-in pad
-- and with the bundled skin picked, so the Skin row (#1386) can be eyeballed.
-- The editor is a top-level love.draw branch in main.lua, not a stack state,
-- so this stands in for that branch and captures the frame itself.
