In table, predicted forward, rolled back
  In table and FTYPEDESC_INSENDTABLE -- controlled by server value which has 
been networked, error checked
  In table and not FTYPEDESC_INSENDTABLE -- rolled forward and back, but not 
received from server, so no error checking
  In table, but FTYPEDESC_PRIVATE -- introspectable (cl_pdump) but not rolled 
forward/back or error checked (may or may not be networked) -- not part of 
prediction really

Not in table
  Unrelated to prediction, not rolled forward back, etc. (rendering variables, 
e.g.)

All of the logic for rewind/prediction is in client .dll in prediction.cpp and 
in prediction_copy.cpp and c_baseentity.cpp, etc...

Subject: [hlcoders] Prediction table questions

I'm unclear on what the prediction table actually achieves. Here is what 
I think might be happening:

*In table:*

    * Prediction error if too far out when next update arrives
    * Memorised when the prediction system rewinds, and restored afterwards

*Not in table: *

    * Not checked for prediction accuracy
    * Can be operated on multiple times as the prediction system rewinds
          o Test prediction->IsFirstTimePredicted() to avoid this

Is this at all accurate? Is there anything else? And:

    * What does it mean to have a var that is the network table but not
      the prediction table?
    * What decides which functions get rewound?
