/*
** Ok, so we changed our minds, and we're not doing this fancy plugin
** stuff for now. There are several reasons:
**
** 1. Plugins were defined as subclasses of applets, but never get their
** own thread of control as applets do. This means although they have all
** the applet features, they never get to start as applets do. Also other
** applets can't find them on the page because they're never started. So
** we decided not to make them applets for now.
**
** 2. All this stuff to give plugins an output stream that feeds back
** into the native NPP_Write proc probably isn't needed. It might be
** nice, but we're not sure. We should get more experience with Java
** reflections of plugins first.
**
** 3. It wasn't implemented anyway.
