The code does not handle an edge case where writing a compressed
image can overflow the avail_out data when doing a flush. Add a
loop to keep writing the data while deflate indicates that it doesn't
have enough space to write out the compressed data during the flush.

The ZipWriter implementation exposes a stateful interface that allows
bytes of data to be streamed in as they arrive. ZipEntries can be
compressed and/or aligned on a 32-bit boundary for mmapping at runtime.
