term_size=($( stty size ))
printf "%b" "\x1B[8;24;80t"

The 24 and 80 in the 'printf' statement can be anything to ALMOST the size of your desktop...
Interesting. What do the outer parentheses around $(stty size) accomplish? I know they are used to force execution in a subshell. But what are they doing here?

I would have gone for
Code:
lines=$(stty size)
lines=${lines% *}

The printf statement doesn't seem to accomplish anything over here. What is it supposed to do? Is that documented somewhere?

In terms of documentation I was looking at this and this.

SYNOPSIS

       package require Tcl  8.4

       package require textutil::tabify

       package require term::ansi::code::macros  ?0.1?

DESCRIPTION

       This package provides higher level control sequences for more complex shapes.

API

   INTROSPECTION
       ::term::ansi::code::macros::names
	      This command is for introspection. It returns as its result a list containing the names of all attribute commands.

       ::term::ansi::code::macros::import ?ns? ?arg...?
	      This  command  imports some or all attribute commands into the namespace ns. This is by default the namespace macros. Note that this
	      is relative namespace name, placing the imported command into a child  of  the  current  namespace.  By  default	all  commands  are
	      imported, this can howver be restricted by listing the names of the wanted commands after the namespace argument.

   SEQUENCES
       ::term::ansi::code::macros::menu menu
	      The  description	of  a  menu  is converted into a formatted rectangular block of text, with the menu command characters highlighted
	      using bold red text.  The result is returned as the result of the command.

	      The description, menu, is a dictionary mapping from menu label to command character.

       ::term::ansi::code::macros::frame string
	      The paragraph of text contained in the string is padded with spaces at the right margin, after normalizing internal tabs,  and  then
	      put into a frame made of box-graphics. The result is returned as the result of the command.
