The plain C bytes array, while convenient from a C perspective, is not well handled by language bindings: the length of the array is not specified, and it's only just implied by the image data size, rowstride, and pixel format. GBytes is a read-only bytes buffer that has an implicit length; we can use it as the storage medium so that language bindings can actually function correctly.
