How is this a feature?  Why is it the case that a widget doesn't want
to override its translations if it's superclass or the client has
specified some other translations.  What is wrong with using
XtOverrideTranslations() or XtAugmentTranslations() to set the
translations in the Initialize method?

This "feature" is used in many Motif widget classes (not just PushButton).
Is there some reason why?  Different translation tables can still be
added with the appropriate Intrinsics routine.  It is not necessary
to set the translation manager translations directly or not set them
if some translations have alreadly been specified.  Is there some
underlying assumption I am missing that mandates this behavior?
