-
-    EGL Extension #XXX
-
-Dependencies
-
-    Requires EGL 1.2.
-
-    EGL_ANDROID_image_native_buffer and EGL_KHR_image_base are required.
-
-    This extension is written against the wording of the EGL 1.2
-    Specification as modified by EGL_KHR_image_base and
-    EGL_ANDROID_image_native_buffer.
-
-Overview
-
-    This extension allows creating an EGLClientBuffer backed by an Android
-    window buffer (struct ANativeWindowBuffer) which can be later used to
-    create an EGLImage.
-
-New Types
-
-    None.
-
-New Procedures and Functions
-
-EGLClientBuffer eglCreateNativeClientBufferANDROID(
-                        const EGLint *attrib_list)

-Changes to Chapter 3 of the EGL 1.2 Specification (EGL Functions and Errors)
-
-    Add the following to section 2.5.1 "EGLImage Specification" (as modified by
-    the EGL_KHR_image_base and EGL_ANDROID_image_native_buffer specifications),
-    below the description of eglCreateImageKHR:
-
-   "The command
-
-        EGLClientBuffer eglCreateNativeClientBufferANDROID(
-                                const EGLint *attrib_list)
-
-    may be used to create an EGLClientBuffer backed by an ANativeWindowBuffer
-    struct. EGL implementations must guarantee that the lifetime of the
-    returned EGLClientBuffer is at least as long as the EGLImage(s) it is bound
-    to, following the lifetime semantics described below in section 2.5.2; the
-    EGLClientBuffer must be destroyed no earlier than when all of its associated
-    EGLImages are destroyed by eglDestroyImageKHR. <attrib_list> is a list of
-    attribute-value pairs which is used to specify the dimensions, format, and
-    usage of the underlying buffer structure. If <attrib_list> is non-NULL, the
-    last attribute specified in the list must be EGL_NONE.
-
-    Attribute names accepted in <attrib_list> are shown in Table aaa,
-    together with the <target> for which each attribute name is valid, and
-    the default value used for each attribute if it is not included in
-    <attrib_list>.

-
-    The maximum width and height may depend on the amount of available memory,
-    which may also depend on the format and usage flags. The values of
-    EGL_RED_SIZE, EGL_GREEN_SIZE, and EGL_BLUE_SIZE must be non-zero and
-    correspond to a valid pixel format for the implementation. If EGL_ALPHA_SIZE
-    is non-zero then the combination of all four sizes must correspond to a
-    valid pixel format for the implementation. The value of
-    EGL_LAYER_COUNT_ANDROID must be a valid number of image layers for the
-    implementation. The EGL_NATIVE_BUFFER_USAGE_ANDROID flag may include any of
-    the following bits:
-
-        EGL_NATIVE_BUFFER_USAGE_PROTECTED_BIT_ANDROID: Indicates that the
-        created buffer must have a hardware-protected path to external display
-        sink. If a hardware-protected path is not available, then either don't
-        composite only this buffer (preferred) to the external sink, or (less
-        desirable) do not route the entire composition to the external sink.
-
-        EGL_NATIVE_BUFFER_USAGE_RENDERBUFFER_BIT_ANDROID: The buffer will be
-        used to create a color-renderable texture.
-
-        EGL_NATIVE_BUFFER_USAGE_TEXTURE_BIT_ANDROID: The buffer will be used to
-        create a filterable texture.
-
-    Errors
-
-        If eglCreateNativeClientBufferANDROID fails, NULL will be returned, no
-        memory will be allocated, and one of the following errors will be
-        generated:
-
-       * If the value of EGL_WIDTH or EGL_HEIGHT is not positive, the error
-         EGL_BAD_PARAMETER is generated.
-
-       * If the combination of the values of EGL_RED_SIZE, EGL_GREEN_SIZE,
-         EGL_BLUE_SIZE, and EGL_ALPHA_SIZE is not a valid pixel format for the
-         EGL implementation, the error EGL_BAD_PARAMETER is generated.
-
-       * If the value of EGL_NATIVE_BUFFER_ANDROID is not a valid combination
-         of gralloc usage flags for the EGL implementation, or is incompatible
-         with the value of EGL_FORMAT, the error EGL_BAD_PARAMETER is
-         Generated.
-
-Issues
-
-    1. Should this extension define what combinations of formats and usage flags
-    EGL implementations are required to support?
-
-    RESOLVED: Partially.
-
-    The set of valid color combinations is implementation-specific and may
-    depend on additional EGL extensions, but generally RGB565 and RGBA888 should
-    be supported. The particular valid combinations for a given Android version
-    and implementation should be documented by that version.
-
-    2. Should there be an eglDestroyNativeClientBufferANDROID to destroy the
-    client buffers created by this extension?
-
-    RESOLVED: No.
-
-    A destroy function would add several complications:
-
-        a) ANativeWindowBuffer is a reference counted object, may be used
-           outside of EGL.
-        b) The same buffer may back multiple EGLImages, though this usage may
-           result in undefined behavior.
-        c) The interactions between the lifetimes of EGLImages and their
-           EGLClientBuffers would become needlessly complex.
-
-    Because ANativeWindowBuffer is a reference counted object, implementations
-    of this extension should ensure the buffer has a lifetime at least as long
-    as a generated EGLImage (via EGL_ANDROID_image_native_buffer). The simplest
-    method is to increment the reference count of the buffer in
-    eglCreateImagKHR, and then decrement it in eglDestroyImageKHR. This should
-    ensure proper lifetime semantics.
