It seems I should pay more attention to the manual "where there's nice
short instructions for creating footprints, which doesn't cover things
like soldermasks though" (and less to the wiki, where there is an
obscure 36-step instruction to create footprints, but it doesn't say
that you should "enable view soldermask as step 14.5").
