I used this utility to check if the possible TGA images' cases for different origins (explictly the Y origin) are generating the same bitmap, as I felt that my eyes are not a good-enough measurement tool for this kind of task. This might be useful in the future for testing other implementations so I rather have this nice utility in our codebase.
