| * Hardware renderer that proxies the rendering to a render thread. Most calls |

| * |
| * The UI thread can block on the RenderThread, but RenderThread must never |
| * block on the UI thread. |
| * |
| * ThreadedRenderer creates an instance of RenderProxy. RenderProxy in turn creates |
| * and manages a CanvasContext on the RenderThread. The CanvasContext is fully managed |
| * by the lifecycle of the RenderProxy. |
| * |
| * Note that although currently the EGL context & surfaces are created & managed |
| * by the render thread, the goal is to move that into a shared structure that can |
| * be managed by both threads. EGLSurface creation & deletion should ideally be |
| * done on the UI thread and not the RenderThread to avoid stalling the |
| * RenderThread with surface buffer allocation. |
