[Gnash] plugin update

[Rob Savoye]

The plugin currently draws a hard-coded graphic in the browser window 
still, but for the folks into really bleeding edge software, if you flip 
the #ifdef in eventThread() to call main_loop instead of drawGLScene(), 
the Flash interpreter is called on the downloaded movie and it plays... :-)

But the display gets lost someplace in the Firefox/OpenGL, and although 
the movies properly advances through all the frames, for some reason I 
only get a blank background. :-( There also seems to be a weird problem 
now where Firefox pops up a little window which then goes away when it 
loads the plugin. More debugging needed, but at least it's getting 
closer to actually working...

I checked it in this way in case there are any OpenGL gurus on the 
list... if not, I'll keep slogging away on it.
