According to the EGL_KHR_platform_gbm extension:

    For each EGLConfig that belongs to the GBM platform, the
    EGL_NATIVE_VISUAL_ID attribute is a GBM color format, such as
    GBM_FORMAT_XRGB8888.

Which we correctly manage. At the same time the EGL 1.4 spec says

    If an EGLConfig supports windows then it may have an associated
    native visual. EGL_NATIVE_VISUAL_ID specifies an identifier for this
    visual, and EGL_NATIVE_VISUAL_TYPE specifies its type. If an
    EGLConfig does not support windows, or if there is no associated
    native visual type, then querying EGL_NATIVE_VISUAL_ID will return 0
    and querying EGL_NATIVE_VISUAL_TYPE will return EGL_NONE.

Based on this, either both of ID and TYPE should be set, or neither.
