Symbols from C++ templates and ABI versioning

[Christoph Egger <christoph@debian.org>]

Hi all!

	Currently irrlicht released a new minor version which I want to
upload to debian. Concerning the ABI the only relecvant change is the
removal of 4 symbols which are template instantiations.

	I can, of course, force instantiation of these templates but that
feels quite like a hack. Does someone with deeper insight into that
topic know if just having that ABI change causes some potential harm
or whether I can just go ahead ignoring it?

Regards

	Christoph
