  * stages to the vertex_buffer TNLcontext::vb, where the vertex data
  * is stored. The last stage in the pipeline is the rasterizer.
  *
- * The initial vertex_buffer data may either come from an ::immediate
- * structure or client vertex_arrays or display lists:
- *
- *
- * - The ::immediate structure records all the GL commands issued between
- * glBegin and glEnd.  \n
- * The structure accumulates data, until it is either full or it is
- * flushed (usually by a state change). Before starting then the pipeline,
- * the collected vertex data in ::immediate has to be pushed into
- * TNLcontext::vb.
- * This happens in ::_tnl_vb_bind_immediate. The pipeline is then run by
- * calling tnl_device_driver::RunPipeline = ::_tnl_run_pipeline, which
- * is stored in TNLcontext::Driver.   \n
- * An ::immediate does (for performance reasons) usually not finish with a
- * glEnd, and hence it also does not need to start with a glBegin.
- * This means that the last vertices of one ::immediate may need to be
- * saved for the next one.
- *
- *
- * - NOT SURE ABOUT THIS: The vertex_arrays structure is used to handle
- * glDrawArrays etc.  \n
- * Here, the data of the vertex_arrays is copied by ::_tnl_vb_bind_arrays
- * into TNLcontext::vb, so that the pipeline can be started.
