extern void (*ufraw_progress)(int what, int ticks);

 * The first call for a PROGRESS_* activity should specify a negative number
 * of ticks. This call will prepare the corresponding progress bar segment.
 * Subsequent calls for the same activity should specify a non-negative number
 * of ticks corresponding to the amount of work just done. The total number
 * of ticks including the initialization call should be approximately zero.
 * This function is thread safe. See also preview_progress().
