measurements—are captured by GDKToolVersionInfo objects.
By default, a tool has just one version (GdkToolInfo_FirstVersion), but more versions may be
added using GdkToolInfo_AddVersion. Whenever the interface of a tool has changed, a new version
can be registered so that the new interface can be correctly parsed by the framework.
When the configuration of a tool instance is saved, the version used at the time is also saved. This saved
version is used by the framework to parse the configuration. If a version not defined by the firmware
implementation, then that tool instance will not be inactive.
During run-time, you can query the version of the configuration of a tool instance by using
GdkToolCfg_Version. You can then interpret the parameters depending on the version the
configuration is saved in.
