/*
see https://developer.mozilla.org/en/NPP_NewStream
NPP_NewStream notifies the plug-in when a new stream is created. The NPStream* pointer is valid
until the stream is destroyed. The plug-in can store plug-in-private data associated with the
stream in stream->pdata. The MIME type of the stream is provided by the type parameter.
The data in the stream can be the file specified in the SRC attribute of the EMBED tag, for an
embedded instance, or the file itself, for a full-page instance. A plug-in can also request a
stream with the function NPN_GetURL. The browser calls NPP_DestroyStream when the stream completes
(either successfully or abnormally). The plug-in can terminate the stream itself by calling
NPN_DestroyStream.
