Hm. The problem is that the inclusion code (internal to libgd) uses the
gdImageColorClosest call as opposed to the gdImageColorClosestAlpha
call. I was hoping that selecting truecolor would avoid that call
altogether. From what I can see, I'd need to include the image pixel by
pixel, in my own code rather than rely on libgd's gdImageCopy. My own
gdImageCopyAlpha. mmmmmmmmmmmmmmmmmmmm.........

I'll see what I can do but this will probably not happen straightaway.
