Yeah you're right I've never worked on 3D computer graphics and I'm
not even really sure what a Sprite is.

The sample class I gave was just an example of a class that has much
more data than metadata. A better example might have been a class that
contains several 512-byte RSA key pairs.

Anyway my argument still stands: The 'memcpy' optimisation for
copy-construction should be usable for polymorphic types (so long as
A: the class is final, or B: we're guaranteed to be dealing with the
most-derived object).
