Subject: [PATCH] fix(decor): unwrap if max width fits 0 chars

The `title_pixmap` function assumed if `title` was not empty, the returned
`glyphs` from `layout_title_glyphs` would also not be empty.
`layout_title_glyphs`, however, could break before a single insertion if
`max_width` was too small. Emacs, when using `emacsclient
--create-frame`, could call `title_pixmap` with a `max_width` of 1,
causing a panic. Closes #311.
