-Version
-
-    Last Modifed Date: Sep 29, 2014
-
-Dependencies
-
-    OpenGL ES 2.0 is required.
-
-    GL_CHROMIUM_image is required.
-
-Overview
-
-    This extension provide a mechanism for creating a GpuMemoryBuffer
-    backed image resource.
-
-Issues
-
-    None
-
-New Tokens
-
-    Accepted by the <usage> parameter of CreateGpuMemoryBufferImageCHROMIUM:
-
-        READ_WRITE_CHROMIUM 0x78F2
-
-New Procedures and Functions
-
-    GLuint CreateGpuMemoryBufferImageCHROMIUM(GLsizei width,
-                                              GLsizei height,
-                                              GLenum internalformat,
-                                              GLenum usage)
-
-    Create a GpuMemoryBuffer backed image with width equal to <width>
-    and height equal to <height> and format equal to <internalformat>.
-
-    Returns a unique identifier for the image that could be used in
-    subsequent operations.
-
-    INVALID_VALUE is generated if <width> or <height> is nonpositive.
-
-    INVALID_ENUM is generated if <internalformat> is not one of
-    RGB or RGBA.
-
-    INVALID_ENUM is generated if <usage> is not READ_WRTIE_CHROMIUM.
-
-    On OS X, driver bugs prevent the usage of memory buffers with RGB internal
-    format. As a workaround, the created GpuMemoryBuffer will always have
-    internal format RGBA. The caller is responsible for handling this
-    appropriately. The only support provided by this extension is that calls
-    that require parameter validation (such as copyTexImage2D and
-    copyTexSubImage2D) will perform paramter validation as if the internal
-    format were RGB.
-
-Errors
-
-    None.
-
-New State
-
-    None.
