/**
* nsIIconURI
*
* This interface derives from nsIURI, to provide additional information
* about moz-icon URIs.
*
* What *is* a moz-icon URI you ask? Well, it has the following syntax:
*
* moz-icon://[<file-uri> | <file-with-extension> | <stock-image>]? ['?'[<parameter-value-pairs>]]
*
* <file-uri> is a legal file: URI spec. You only need to specify a file: URI inside the icon
* if the file you want the icon for actually exists.
*
* <file-with-extension> is any filename with an extension, e.g. "dummy.html".
* If the file you want an icon for isn't known to exist, you can omit the file URI, and just
* place a dummy file name with the extension or content type you want: moz-icon://dummy.html.
*
* <stock-image> is of the format: stock/<icon-name>
*
* <icon-name> is a valid icon name, such as 'ok', 'cancel', 'yes', 'no'.
* XXXcaa Should these considered platform dependent or can we share and document them?
*
* Legal parameter value pairs are listed below:
*
* Parameter: size
* Values: [<integer> | button | toolbar | toolbarsmall | menu | dialog]
* Description: If integer, this is the desired size in square pixels of the icon
* Else, use the OS default for the specified keyword context.
*
* Parameter: state
* Values: [normal | disabled]
* Description: The state of the icon.
*
* Parameter: contentType
* Values: <mime-type>
* Description: The mime type we want an icon for. This is ignored by stock images.
