* Replace supported image extension list with image detection via MagickImageInfo. * Change ImageViewer priority to -4. Change VideoViewer priority to -3 and detect audio/video via MediaInfo instead of file extensions. * Make mediaInfo a class static and initialize once. Add some notes about MediaInfo Open and Close. * Remove try/catch from Prepare and let it be handled in caller. If there was an exception due to MediaInfo it would have already occurred in CanHandle. * Upgrade ImageMagick to latest * Only check extension for well known image and animated image types. For other image formats, let ImageMagick try to detect by file content. Upgrade to latest Magick.NET Co-authored-by: Frank Becker <frank.becker@thoughtexchange.com>
