Let a pane's tag take a row for each line it holds

A tag that is a text can hold a newline, and the tagline, the body under it
and the pointer all assumed one row. The pane's tag now takes a row per line
(up to eight, and never the body's last row); the body starts below it, the
rows a pointer counts start the body after the tag's lines, a click on any
line puts the tag's cursor there, and a pixel shell gets a tag layer per
line. A tag of one line draws exactly as before.
