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.

DESCRIPTION

       This package provides symbolic names for the ANSI attribute control codes. For each control code a single command is provided which returns
       this code as its result. None of the commands of this package write  to	a  channel;  that  is  handled	by  higher  level  packages,  like
       term::ansi::send.

API

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

       ::term::ansi::code::attr::import ?ns? ?arg...?
	      This  command imports some or all attribute commands into the namespace ns. This is by default the namespace attr. 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.
