From: Emil Velikov <emil.veli...@collabora.com>
Only the X11+DRI2 platform supports it and AFAICT only Chrome uses it.
Other EGL implementations, barring the Nvidia one, do not implement the
extension.
Which is understandable since it is superseded by EGL_EXT_buffer_age,
EGL_KHR_swap_buffers_with_damage and/or EGL_KHR_partial_update.
