In the HGE tutorials, sprites are created in this manner, so I adapted
the method to work with arrays.

Thank you very much for this tip. I seem to remember that hgeSprite does
have a functioning copy constructor, so I should give the vector method
a go. Before I get there, I have to gain a better understanding of OOP
programming so I don't find myself hacking and experimenting with the
std::vector functions. Too much of my time is spent doing this, I'm
ashamed to admit :(

Another reason to get myself familiarized with all that C++ has to
offer. Thank you for your feedback!
