[devel] IDAT compression failed if preceded by a compressed text chunk This was because the attempt to reset the zlib stream in png_write_IDAT happened after the first IDAT chunk had been deflated - much too late. In this change internal functions are added to claim/release the z_stream and, hopefully, make the code more robust. Also deflateEnd checking is added - previously libpng would ignore an error at the end of the stream.
