 Attached is a patch for the Nginx portfile that adds three new variants:

 '''+image_filter''' - Enables the Nginx image filter module
 (http://wiki.nginx.org/HttpImageFilterModule) [[BR]]
 '''+mp4''' - Enables the Nginx MP4 streaming module
 (http://wiki.nginx.org/HttpMp4Module) [[BR]]
 '''+xslt''' - Enables the Nginx XSLT filtering module
 (http://wiki.nginx.org/HttpXsltModule)

 I'm new to the art of portfile writing, so suggestions are welcome!
