sub debug_timer_start {
$blurb = 'Starts measuring elapsed time.';
$help = <<'HELP';
This procedure starts a timer, measuring the elapsed time since the call.
Each call to this procedure should be matched by a call to
gimp_debug_timer_end(), which returns the elapsed time.
If there is already an active timer, it is not affected by the call, however, a
matching gimp_debug_timer_end() call is still required.

sub debug_timer_end {

$help = <<'HELP';
This procedure stops the timer started by a previous gimp_debug_timer_start()
call, and prints and returns the elapsed time.
If there was already an active timer at the time of corresponding call to
gimp_debug_timer_start(), a dummy value is returned.
