EGL_EXT_Compositor example and behavior

I’m trying to understand the usage of the EXT_compositor extension.

The easiest way after reading the description of the extension is to see some usage example. But no luck, I didn’t find any example at all. So, does anyone have and can please upload some usage sample code? And my main question regarding the extension: what is the policy of overlapping windows? Is it just the windows order at attributes list or there’s a blend option between the windows?

The extension does not provide any idea of overlapping windows. It simply provides a producing application the ability to render to an EGLSurface object. It then provides the Compositing application the ability to read that RGBA buffer as a texture object to OpenGL. The Compositing application can then layer the textures in any way it wants.
