tests: test_png_regress
I want to make some changes to the PNG loader, this is to get some test coverage at least to make it easier not to break anything. The two ref_results files that are "corrupt" files that stb_image nevertheless loads without error are checksum failures; this is by design, since stb_image does not verify checksums.
