 Constructor

 Lock the object in mode 'lock'. Return TRUE if successful, FALSE
 if the object is already locked.

 Release current lock, make sure it the same as the 'lock' argument.
 Returns TRUE on success, FALSE on failure.

const char* LockName(TGLLockable::ELock lock)

 Return name-string for given lock-type.

 Test if lock is a valid type to take/release.
 kUnlocked is never valid in these cases.
