GtkGLArea cannot work properly with Broadway, because when you use Broadway, 
you don't have any X11/Win32 context at all. You're just drawing to a pixbuf 
rendered via a HTML5 canvas. 

BTW, WebGL is the only well-known method to use OpenGL is a browser. But I 
don't see how it could be implemented in GTK+ (you'd have to generate WebGL 
client-side code on the fly... pure hell). So I'd classify this as NOTABUG 
personally ;-)

Your code doesn't use GtkGLArea at all, but GLX ; so yes, it obviously is 
Unix-specific and needs X11. GtkGLArea was designed to avoid this, by using 
GLX on X11, and WGL on Windows, transparently. 

So if you'd use GtkGLArea, you'd have a single code and recompile it with no 
changes on Unix and Win32. That's the whole point of the library.
