54 * Process the list of render-tasks; the output is a series of render instructions.
55 * @note When ProcessRenderTasks is called, the layers should already the transparent/opaque renderers which are ready to render.
56 * If there is only one default render-task, then no further processing is required.
57 * @param[in] updateBufferIndex The current update buffer index.
58 * @param[in] renderTasks The list of render-tasks.
59 * @param[in] rootNode The root node of the scene-graph.
60 * @param[in] sortedLayers The layers containing lists of opaque / transparent renderables.
61 * @param[out] instructions The instructions for rendering the next frame.
