pub type WebPWriterFunction = Option<extern "C" fn(*const u8, usize, *const WebPPicture) -> c_int>;

Signature for output function. Should return true if writing was successful. data/data_size is the segment of data to write, and picture is for reference (and so one can make use of picture->custom_ptr).
