We are loading png dynamically and we want to keep doing that. Figure<br>
out where the longjmp call comes from (perhaps it is some macro or so<br>
in the png code). We might have to dynamically load the function..<br>
<br>
Regarding that gray conversion function. The only thing that changed<br>
is the name of the function the prototype and its behavior looks<br>
similar. I'm not sure how we want to fix it. For instance it can be<br>
fixed at compile time by checking the png version (I believe png.h<br>
defines it) or it can be done at runtime by checking if the old<br>
function is around and if it isn't try to load the new function.<br>
