<p>Creates a new timeout pool source. A timeout pool should be used when
multiple timeout functions, running at the same priority, are needed and
the <code class="function">g_timeout_add()</code> API might lead to starvation of the time slice of
the main loop. A timeout pool allocates a single time slice of the main
loop and runs every timeout function inside it. The timeout pool is
always sorted, so that the extraction of the next timeout function is
a constant time operation.</p>

<p>Sets a function to be called at regular intervals, and puts it inside
the <em class="parameter"><code>pool</code></em>
. The function is repeatedly called until it returns <code class="literal">FALSE</code>,
at which point the timeout is automatically destroyed and the function
won't be called again. If <em class="parameter"><code>notify</code></em>
is not <code class="literal">NULL</code>, the <em class="parameter"><code>notify</code></em>
function
will be called. The first call to <em class="parameter"><code>func</code></em>
will be at the end of <em class="parameter"><code>interval</code></em>
.</p>
<p>Since Clutter 0.8 this will try to compensate for delays. For
example, if <em class="parameter"><code>func</code></em>
takes half the interval time to execute then the
function will be called again half the interval time after it
finished. Before version 0.8 it would not fire until a full
interval after the function completes so the delay between calls
would be <em class="parameter"><code>interval</code></em>
* 1.5. This function does not however try to
invoke the function multiple times to catch up missing frames if
<em class="parameter"><code>func</code></em>
takes more than <em class="parameter"><code>interval</code></em>
ms to execute.</p>

<p>Sets a function to be called at regular intervals with the given
priority. The function is called repeatedly until it returns
<code class="literal">FALSE</code>, at which point the timeout is automatically destroyed and
the function will not be called again. The <em class="parameter"><code>notify</code></em>
function is
called when the timeout is destroyed. The first call to the
function will be at the end of the first <em class="parameter"><code>interval</code></em>
.</p>
<p>This function is similar to <code class="function">g_timeout_add_full()</code> except that it
will try to compensate for delays. For example, if <em class="parameter"><code>func</code></em>
takes half
the interval time to execute then the function will be called again
half the interval time after it finished. In contrast
<code class="function">g_timeout_add_full()</code> would not fire until a full interval after the
function completes so the delay between calls would be 1.0 / <em class="parameter"><code>fps</code></em>
*
1.5. This function does not however try to invoke the function
multiple times to catch up missing frames if <em class="parameter"><code>func</code></em>
takes more than
<em class="parameter"><code>interval</code></em>
ms to execute.</p>
<p>Rename to: clutter_frame_source_add</p>
