Comment (by dreammaster):

 Thanks for letting me know. That correlates with what I saw when I hacked
 the code to ignore the assert. But of course since the PNG decoder is a
 core ScummVM class, I can't just disable the check. But I think I've got a
 handle on it. The transparency data does indeed seem to be alpha values
 for each of the palette entries, and the transparency color always has to
 start at palette index 0. So previously, we only had PNGs that had the
 single transparent color that was fully transparent.

 So in cases such as this PNG, I should be able to do a proper
 implementation that creates the decoded image as a full RGBA rather than
 an 8-bit image with a seperate RGB palette being specified. In theory :)
