Chris, I've also done some work toward pure EGL support, intending to improve support for Android in OSG. How far along is your EGL work? I've got most of the EGL context and surface management done in implementations of osg::GraphicsContext::WindowingSystemInterface and osgViewer::GraphicsWindow.
I could separate the pure EGL calls from my Android-specific code to create a osgViewer::GraphicsWindowEGL that implements closeImplementation() makeCurrentImplementation() realizeImplementation() releaseContextImplementation() swapBuffersImplementation() Then, it would be straightforward to subclass GraphicsWindowEGL to make a GraphicsWindowAndroid or a GraphicsWindowLinuxEGL that would implement the remaining virtuals like GraphicsWindow::checkEvents(). Thoughts?

Did you get it running without x11? Yes. However, there was a lot of OSG Windows and Linux support code that needed writing and updating in order to support pure EGL calls (instead of EGL calls that also rely on X11), so we ended up creating the EGL context outside of OSG and using osgViewerEmbedded, which worked ok. If you're interested in having full and proper EGL support, we could possibly pick up the work I began, and finish it in a reasonable amount of budget. -- Chris 'Xenon' Hanson, omo sanza lettere.
