A Packet is a generic gpu instruction to draw on screen....
Packets have variable size, so an average size is normally set.
I normally just allocate 64k for my workspaces but the sample code always
used n*24, where n is the expected max number of polys.
As these depend on your game/demo a good check is to record the maximum
amount used ( using GsGetWorkBase after you have built your polys. ) and
adjust or warn according to the result.

Cheers,

Colin.
