Not that I'm aware of, but I'm sure you'd need to write some code for
Gnash to do what you want it to do, so you'll be compiling it anyway.

I can't really answer your question accurately without more information
about what you want to do. It is, of course, possible to have Gnash
rendering into a separate OpenGL window using (at least GTK). But if you
really want Gnash to render into the same OpenGL context as your
existing application, you'll basically have to hack Gnash.

My best guess would be that you have an OpenGL application that, among
other things, you want to display SWFs in. Now, the way I see it, the
easiest way to do that would be to provide a new Gnash GUI that merely
delivers a bitmap to your application when an SWF frame has been
rendered, so you can simply plaster that into your OpenGL scene and use
it as a texture or something along those lines.
