// This class (along with other CryInput/AzToLyInput* classes) is just a temporary bridge that we must
// use to translate AzFramework Input events back to CryInput events, until such time as we are able
// to deprecate and then completely remove CryInput. This is because on almost all platforms it is
// not possible for two different systems to process the raw input obtained from the various system
// APIs, so although we need to maintain the CryInput interface for a time we must make it depend
// on AzFramework Input in the interim.
