The surfaceless extension that Mesa advertises has been renamed to EGL_KHR_surfaceless_context instead of a separate extension for the GLES, GLES2 and GL APIs and the new extension has been ratified by Khronos. Therefore the KMS backend no longer runs against Mesa master. We could just rename the extension we check for, however Weston (the sample Wayland compositor) has switched to just creating a dummy GBM surface and not using the surfaceless extension at all. We should probably do the same thing. Using the surfaceless extension could be a good idea but we don't really need to rely on it for KMS and we would want to do it for all EGL backends, not just the KMS backend.
