atrf-path: new option -T to sweep only one offset

Browse Source 
atrf-path -T +0.5 -g ... 10 10 time:

before (both offsets)	0.65 s
after (one offset)	0.32-0.33 s	(50%)

- atrf-path.c (usage, main): new option -T to specify which offset to
  sweep (default: sweep both)
- atrf-path.c (do_half_sweep): only sample points with the desired offset
- atrf-path.c (print_sweep): only prints points we've sweeped
- gui.c (segment, draw): inverted flag logic from "have_last" to "first"
- gui.c (draw): only plot points we've sweeped
- gui.c (gui): pass the offset selection to "draw"
