- solidify/Makefile (OBJS): added overlap.o - solidify/Makefile (CFLAGS): added -O9 to speed up rotation a little - solidify/array.h, solidify/array.c (get_bounded): like get(), but returns UNDEF if the indices are outside the array - solidify/face.h (struct face, struct matrix), solidify/face.c (read_file): added a 2D transformation matrix to "struct face" - solidify/overlap.h, solidify/overlap.c: show a face with 2D transformation
