Can be enabled/disabled at runtime by toggling the 'media.jxr.enabled' pref (disabled by default). Two additional prefs are provided for testing purposes: 'media.jxr.autoaccept', and 'media.jxr.advertised_mime_type' See comments in all.js for information on what these do. This commit includes the MS OpenTech implementation of the decoder on the browser side with some fixes applied; see the development in Pale Moon GitGub issue #105 or my comments in the source code for more information.
