public void setIcons(Object[] value) {
        put("Icons", value);
    }
Sets the application icons to be used, with the most preferred first.
For Windows, you should supply at least one 16x16 icon and one 32x32. The former is used for the title/task bar,
the latter for the alt-tab icon.
Linux (and similar platforms) expect one 32x32 icon.
Mac OS X should be supplied one 128x128 icon.
<br>
The icon is used for the settings window, and the LWJGL render window.
Note that a bug in Java 6 (bug ID 6445278, currently hidden but available in Google cache) currently prevents
the icon working for alt-tab on the settings dialog in Windows.

@param value An array of BufferedImages to use as icons.
(Default: not set)
