-  // If share_context is not NULL, then all shareable data, as defined

-  // this fashion.

-  // attrib_list specifies a list of attributes for the context. It is a list
-  // of attribute name-value pairs in which each attribute is immediately

-  // Attributes that can be specified in attrib_list include:
-  // - PP_GRAPHICS3DATTRIB_ALPHA_SIZE: Category: AtLeast Default: 0.

-  // context and reinitialize client API state and objects to continue
-  // rendering.
-  //
-  // Note that the same error code is also returned in the SwapBuffers callback.

-  //   is less than zero.

-  // to any plugin instance. The contents of ancillary buffers are always
-  // undefined after calling SwapBuffers. The contents of the color buffer are
-  // undefined if the value of the PP_GRAPHICS3DATTRIB_SWAP_BEHAVIOR attribute
-  // of context is not PP_GRAPHICS3DATTRIB_BUFFER_PRESERVED.
-  //
-  // SwapBuffers runs in asynchronous mode. Specify a callback function and the
-  // argument for that callback function. The callback function will be executed
-  // on the calling thread after the color buffer has been composited with
-  // rest of the html page. While you are waiting for a SwapBuffers callback,
-  // additional calls to SwapBuffers will fail.
-  //
-  // Because the callback is executed (or thread unblocked) only when the
-  // plugin's current state is actually on the screen, this function provides a
-  // way to rate limit animations. By waiting until the image is on the screen
-  // before painting the next frame, you can ensure you're not generating
-  // updates faster than the screen can be updated.
-  //
-  // SwapBuffers performs an implicit flush operation on context.
-  // If the context gets into an unrecoverable error condition while
-  // processing a command, the error code will be returned as the argument
-  // for the callback. The callback may return the following error codes:
-  // - PP_ERROR_NOMEMORY
-  // - PP_ERROR_CONTEXT_LOST
-  // Note that the same error code may also be obtained by calling GetError.
-  //

-  // - PP_ERROR_BADRESOURCE if context is invalid.
-  // - PP_ERROR_BADARGUMENT if callback is invalid.
