Thanks for the hard work, Ken, but I think I officially claim defeat
on this. After using your patch I got a few obvious errors then ran
into this (pasted below).
Thanks again,
Charlie

running up against fundamental limitations of the compiler. If that
is the case, then changing from one implementation of the STL to
another probably won't do anything.>> I'm not following John's comment about the animation blit... I

without the _wxagg module, but it won't be as fast.> Sounds great. I'll be more than happy to test out any of your

Debian Stable. I'm not confident it will work under windows... as I
was wrapping it up I found that boost.org claims that "a template
cannot be declared a friend of a class" [1]. I guess it's worth a
shot, though.Ken
