 <p>The recoverable error conditions that have no side effect are detected and returned immediately by all functions in this interface. In addition the implementation may get into a fatal state while processing a command. In this case the application must destroy the context and reinitialize client API state and objects to continue rendering.</p>
 <p>Note that the same error code is also returned in the SwapBuffers callback. It is recommended to handle error in the SwapBuffers callback because GetError is synchronous. This function may be useful in rare cases where drawing a frame is expensive and you want to verify the result of ResizeBuffers before attempting to draw a frame.</p>

 <p>This function has no effect on off-screen surfaces - ones not bound to any plugin instance. The contents of ancillary buffers are always undefined after calling <code>SwapBuffers</code>. The contents of the color buffer are undefined if the value of the <code>PP_GRAPHICS3DATTRIB_SWAP_BEHAVIOR</code> attribute of context is not <code>PP_GRAPHICS3DATTRIB_BUFFER_PRESERVED</code>.</p>
 <p><code>SwapBuffers</code> 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.</p>
 <p>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.</p>
 <p>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:</p>
 <ul>
 <li><code>PP_ERROR_NOMEMORY</code></li>
 <li><code>PP_ERROR_CONTEXT_LOST</code> Note that the same error code may also be obtained by calling GetError.</li>
