Window Opening Functions - Description

This script currently contains functions that:

All windows (except the full screen window) can be given status bars, scrollbars or other properties. If a window with the same HTML name is open, this window will be given focus when the new document is loaded into it.

A function to open a full-chrome window (one which has all the toolbars and menus) is also included. This mimics the behaviour of a link that has the target attribute set to _blank but has the benefit of giving focus to the window and returning a javascript reference to it.

A number of functions that allow popup windows to closely mimic modal dialog window behaviour are also included. Modal dialogs are windows that interrupt the user's use of an application and maintain focus until the user completes the task the dialog is presenting. The native Javascript alert() method is an example.

Note for Gecko-based browsers: Unless you specify otherwise, Gecko will assume that all images are inline and are given a default vertical-align of baseline which results in a gap of several pixels at the bottom of all images. What has this got to do with windows? If you size your popups to exactly fit an image, you'll end up with a vertical scrollbar (and maybe a horizontal one forced by the appearance of the vertical one). Set display: block on the image to make the gap disappear (which will remove the scrollbars).
