The Zobject.js array:

ID Value Description
screen.availHeight Available height of the monitor display, in pixels.
screen.colorDepth Color bit depth. (ie: 8bit = 256 colors, etc...)

There's not too much to these first functions, but they set the groundwork for all the others.
  • Zobject.js
    Foobar, blah.
These values will change constantly, which accounts for the Zupdater script.
