[Gnash] plugin checkin

[Rob Savoye]

I checked in another version of the plugin. This one draws a triangle 
and box in the window where the image is supposed to be rendered. This 
may be boring, but it's correctly working when there are multiple Flash 
movies on a page, each executing in it's own thread. I've been learning 
all about the OpenGL global context in a threaded application today, oh 
fun... At least it's getting closer.

This doesn't need the hard coded path to a texture file, so it should 
work for more people without editing. It still downloads all the Flash 
movies it sees to /tmp. At least it runs without hanging Firefox, or 
crashing. Now I'll go back to merging the player into the plugin code.
