[Quake-C] DP Netgraph (shownetgraph)

[Cobalt <co...@te...>]

As per Lord Havoc, setting shownetgraph to 1 in console brings up the 
Darkplaces
built in netgraph showing incoming and outgoing netpacket details for the 
current connection to the server.

=============================================
Darkplaces Netgraph Color breakdown as per Lord Havoc :
=============================================
Red vertical line - lost packet
Yellow dot - choked packet (rate limiting, no packet created because of 
recent packets exceeding tolerances)
Green dot - acknowledgement for receiving reliable message.
White - reliable message (centerprint, chat, etc).
Orange - unreliable message (entities, effects, etc).
==============================================

I have a white dot appearing at a regular interval on the incoming which is 
more than likely a stray centerprint, but in the Quake C I am having a hard 
time finding whats doing it. I tried cl_shownet 2 in console but no 
centerprint services seem to be listed in the breakdown.

Any ideas on how to isolate the issue such as a way to inspect the udp 
packets?
