FMod - Missing tile detection not so simple

I did some investigation on how easy it would be to make Abiathar detect and flag tiles that are missing from the EGA resources. Doing that wouldn't be terribly inconvenient, but unfortunately I don't think it would be very helpful. The users who need it most are those who load the original game graphics, but for speed and size Abiathar keeps those in GIF format, not as EGA resources. The apparent blankness of the faux-blank tiles is baked into those tilesets by the program I used to export them. Anything having to do with the EGA loader obviously can't affect bitmap-graphics users, so all the people who just use bitmap graphics for the convenience of not needing to reimport all the time also wouldn't be helped. Finally, the people who do load EGA graphics are doing that because the graphics are modified. I'm pretty sure all import programs in common use don't leave tile chunks missing, so there would be no missing chunks to flag. Therefore, it doesn't seem like this feature would be very helpful.
