[semidet]write_size(+Term, -Width, -Height, +Options)

True when Width and Height describe the maximum line width and Height the number of lines for printing Term using Options using write_term(Term, Options). The computed width is a count of display columns, as in line_position/2: it respects Unicode combining and double width characters and does not count ANSI escape sequences. In addition to qvalid options for write_term/2, it processes the options:

max_width(+MaxWidth)
max_height(+MaxHeight): If provided, fail if Width or Height would be larger than the specified maximum. The implementation ensures that the runtime is limited when computing the size of a huge term with a bounded maximum.
