The file parameter of the XBM image ZPP is not properly taken into account. If it is NULL that would result in a segfault, because gdImageXbmCtx() is not prepared to take a NULL file_name. If it is not NULL the XBM data would be written to STDOUT, because the stream is not initialized. This patch fixes both issues.
