CG_PredictPlayerState
Generates cg.predictedPlayerState for the current cg.time
cg.predictedPlayerState is guaranteed to be valid after exiting.
For demo playback, this will be an interpolation between two valid
playerState_t.
For normal gameplay, it will be the result of predicted usercmd_t on
top of the most recent playerState_t received from the server.
Each new snapshot will usually have one or more new usercmd over the last,
but we simulate all unacknowledged commands each time, not just the new ones.
This means that on an internet connection, quite a few pmoves may be issued
each frame.
OPTIMIZE: don't re-simulate unless the newly arrived snapshot playerState_t
differs from the predicted one. Would require saving all intermediate
playerState_t during prediction.
We detect prediction errors and allow them to be decayed off over several frames
to ease the jerk.

MODEL TESTING
The viewthing and gun positioning tools from Q2 have been integrated and
enhanced into a single model testing facility.
Model viewing can begin with either "testmodel <modelname>" or "testgun <modelname>".
The names must be the full pathname after the basedir, like
"models/weapons/v_launch/tris.md3" or "players/male/tris.md3"
Testmodel will create a fake entity 100 units in front of the current view
position, directly facing the viewer. It will remain immobile, so you can
move around it to view it from different angles.
Testgun will cause the model to follow the player around and supress the real
view weapon model. The default frame 0 of most guns is completely off screen,
so you will probably have to cycle a couple frames to see it.
"nextframe", "prevframe", "nextskin", and "prevskin" commands will change the
frame or skin of the testmodel. These are bound to F5, F6, F7, and F8 in
q3default.cfg.
If a gun is being tested, the "gun_x", "gun_y", and "gun_z" variables will let
you adjust the positioning.
Note that none of the model testing features update while the game is paused, so
it may be convenient to test with deathmatch set to 1 so that bringing down the
console doesn't pause the game.
