+/* The simplest 'middle end' in the new vertex code.
+ *
+ * The responsibilities of a middle end are to:
+ * - perform vertex fetch using
+ * - draw vertex element/buffer state
+ * - a list of fetch indices we received as an input
+ * - run the vertex shader
+ * - cliptest,
+ * - clip coord calculation
+ * - viewport transformation
+ * - if necessary, run the primitive pipeline, passing it:
+ * - a linear array of vertex_header vertices constructed here
+ * - a set of draw indices we received as an input
+ * - otherwise, drive the hw backend,
+ * - allocate space for hardware format vertices
+ * - translate the vertex-shader output vertices to hw format
+ * - calling the backend draw functions.
+ *
+ * For convenience, we provide a helper function to drive the hardware
+ * backend given similar inputs to those required to run the pipeline.
+ *
+ * In the case of passthrough mode, many of these actions are disabled
+ * or noops, so we end up doing:
+ *
+ * - perform vertex fetch
+ * - drive the hw backend
+ *
+ * IE, basically just vertex fetch to post-vs-format vertices,
+ * followed by a call to the backend helper function.
