atrf-path: added visual history of dumps

Browse Source 
- gui.c (segment, draw, gui): make caller provide color, to ease sharing
- gui.c (dump, gui): moved call to print_sweep to separate function
- gui.c (DUMP_RGBA, dumps, n_dumps, dump, draw_dumps, gui): record all
  dumps and display them in the background
