- sweep.h (MIN_DIFF, MAX_DIFF, struct sweep): added min/max profile - sweep.h (do_sweep), atrf-path.c (do_half_sweep, do_sweep): compare result against limits and return pass/fail decision - sweep.h (N_CHAN), atrf-path.c (do_half_sweep, do_sweeps), gui.c (N_CHAN): declare number of channels in one central place instead of scattering it all around the program - atrf-path.c (do_read_profile, read_profile, usage, main): new option -P to read a min/max profile - gui.c (indicate, main): moved indicator to separate function and improved blink logic - gui.c (OVER_RGBA, UNDER_RGBA, indicate, main): change color to indicate pass/fail
