/**
* 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)
