XGetExtensionVersion - query the version of the input extension.

           The XGetExtensionVersion request is deprecated and should not
           be used in XI2 applications. Clients issuing a XGetExtensionVersion
           request will not be able to use XI2 features.

           The XGetExtensionVersion request queries the version of the input
           extension, and returns an XExtensionVersion structure. This structure
           contains a major_version and minor_version number which can be compared
           with constants defined in XI.h. Support for additional protocol
           requests added to the input extension after its initial release
           is indicated by a version number corresponding to the added
           requests. Each version contains all the protocol requests
           contained by previous versions.

           You should use XFree to free the XExtensionVersion structure.
