- solidify/Makefile, solidify/histo.h, solidify/histo.c: generate a Z histogram and find the median height - solidify/face.c (read_face): set z_ref to the median, not the average - solidify/face.c (read_face): uncompress .bz2 files on the fly - solidify/face.c (read_face): don't close standard input (for style)
