EGL_EXT_platform_device looks interesting but I don't see how to use it. Looks like already used for ANGLE: https://searchfox.org/mozilla-central/rev/973000acec0cbf7211e0fad89ca00c352aeb8384/gfx/gl/GLLibraryEGL.cpp#210 but I don't see any eglCreateDeviceANGLE() Linux equivalent. Do we need to enumerate the devices or so? The whole bunch of related extenstion (GL_EXT_device_base EGL_EXT_device_enumeration EGL_EXT_device_query) is a bit cryptic to me.
