* <B>INTERFACE TO NETSCAPE COMMUNICATOR PLUGINS (NEW C++ API).</B>
*
* <P>This superscedes the old plugin API (npapi.h, npupp.h), and
* eliminates the need for glue files: npunix.c, npwin.cpp and npmac.cpp that
* get linked with the plugin. You will however need to link with the "backward
* adapter" (badapter.cpp) in order to allow your plugin to run in pre-5.0
* browsers.
*
* <P>See nsplugin.h for an overview of how this interface fits with the
* overall plugin architecture.

/**
* The nsIPlugin interface is the minimum interface plugin developers need to
* support in order to implement a plugin. The plugin manager may QueryInterface
* for more specific plugin types, e.g. nsILiveConnectPlugin.
*
* The old NPP_New plugin operation is now subsumed by two operations:
*
* CreateInstance -- called once, after the plugin instance is created. This
* method is used to initialize the new plugin instance (although the actual
* plugin instance object will be created by the plugin manager).
*
* nsIPluginInstance::Start -- called when the plugin instance is to be
* started. This happens in two circumstances: (1) after the plugin instance
* is first initialized, and (2) after a plugin instance is returned to
* (e.g. by going back in the window history) after previously being stopped
* by the Stop method.
