- * - Upload RGB texture with known content. |
- * - Draw the RGB texture onto the EglBase with the SurfaceTexture as target. |

- * - Create an EglBase with a pixel buffer as target. |
- * - Render the OES texture onto the pixel buffer. |
- * - Read back the pixel buffer and compare it with the known RGB data. |
