<p>Starts measuring elapsed time.</p>
<p>This procedure starts a timer, measuring the elapsed time since the
call. Each call to this procedure should be matched by a call to
<a class="link" href="libgimp-gimpdebug.html#gimp-debug-timer-end" title="gimp_debug_timer_end ()"><code class="function">gimp_debug_timer_end()</code></a>, which returns the elapsed time.
If there is already an active timer, it is not affected by the call,
however, a matching <a class="link" href="libgimp-gimpdebug.html#gimp-debug-timer-end" title="gimp_debug_timer_end ()"><code class="function">gimp_debug_timer_end()</code></a> call is still required.</p>

point, and should not be used in production.</p>

<a class="link" href="libgimp-gimpdebug.html#gimp-debug-timer-start" title="gimp_debug_timer_start ()"><code class="function">gimp_debug_timer_start()</code></a> call, and prints and returns the elapsed
time.

call to <a class="link" href="libgimp-gimpdebug.html#gimp-debug-timer-start" title="gimp_debug_timer_start ()"><code class="function">gimp_debug_timer_start()</code></a>, a dummy value is returned.</p>
