  * coders/png.c: Added support for a proposed new PNG chunk
    (zxIf, read-only) that is currently being discussed on the

    exIf and zxIf with CPPFLAGS="-DexIf_SUPPORTED -DxzIf_SUPPORTED".
    If exIf is enabled, only the uncompressed exIF chunk will be
    written and the hex-encoded zTXt chunk containing the raw Exif
    profile won't be written.

    conflicts with other applications that also use the oFFs chunk.

    read-write, eXIf read-only) that is currently being discussed on the
