+ * For non-indexed drawing, this function helps work around hardware

+ *
+ * For the given mode of primitive from info, calculate the count and

+ *
+ * \param info pointer to the original pipe_draw_info from draw_vbo
+ * \param max_verts max number of vertices that can be handled by the hardware
+ * \param count number of vertices remaining in the draw call. It is also
+ * used as a return parameter, containing how many vertices
+ * should be sent in the next job to the hardware.
+ * \param step return parameter, will contain how many vertices should be
+ * skipped from the original count on the next call to this
+ * function (may differ from count if the primitive mode
+ * requires the last vertices to be reused in the next draw)
