/** \defgroup rdpSettings rdpSettings
* \brief This is the FreeRDP settings module.
*
* Settings are used to store configuration data for an RDP connection.
* There are 3 different settings for each client and server:
*
* 1. The initial connection supplied by the user
* 2. The settings sent from client or server during capability exchange
* 3. The settings merged from the capability exchange and the initial configuration.
*
* The lifetime of the settings is as follows:
* 1. Initial configuration is saved and will be valid for the whole application lifecycle
* 2. The client or server settings from the other end are valid from capability exchange until
* the connection is ended (disconnect/redirect/...)
* 3. The merged settings are created from the initial configuration and server settings and
* have the same lifetime, until the connection ends
*
*
* So, when accessing the settings always ensure to know which one you are operating on! (this
* is especially important for the proxy where you have a RDP client and RDP server in the same
* application context)
*
