I'm packaging gif and we always run cargo test to ensure that library works fine in distribution. But unfortunately gif one fails (I assume because you exclude test data). Could you either include it or make it to not fail in case data is missing? Thanks.

This reminded me, I've just opened a PR on image that could ensure that tests can be ran with the archives from crates. You might want to have a look, and I'll see when I get around to porting it to gif for additional data points of usage. (Or just relay the message to other interested parties at Gnome).

I've moved some tests out, but that wasn't sufficient. There are still tests inline in .rs files that are published, so this is WONTFIX.
