3.1.6 Initialization
There is no specific initialization for the Remote Desktop Protocol: Geometry Tracking Virtual Channel Extension. Each message is wholly self-contained and, since the network transport is assumed to be lossless, current. Each message will contain either geometry specific to a particular mapping (which MUST then be either updated if known or created if not known) or instructions to clear a mapping if it exists. Aside from this logic, there is no additional handling or processing necessary.
