Two main tests: read the file and compare to a given image (loaded from png), and write a file out and compare to a previously-written image. The write test in particular is kind of fragile, but it should help catch some errors where a code change was not intended to affect the output of the plugin. Tests are included for all the writable formats, as well as every readable format that GIMP can write to (and so I could easily get an example of). REVIEW: 115430
