-- neovim has a NormalNC highlight group that applies to inactive windows but
-- we want to apply different styles to *active* windows. The Normal highlight
-- group is special and setting a background there applies to everything and
-- cannot be "unset" from other groups like NormalNC.
--
-- What we do here is create a new highlight namespace that we apply to active
-- windows only. We have to copy all the original highlight groups and then
-- apply our changes. We then change the window's highlight namespace on
-- WinEnter/WinLeave.
