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\&.
