Use this for default priority event sources.
In GLib this priority is used when adding timeout functions with
<a class="link" href="glib-The-Main-Event-Loop.html#g-timeout-add"><code class="function">g_timeout_add()</code></a>.
In GDK this priority is used for events from the X server.

<p>
Use this for high priority idle functions.
GTK+ uses <a class="link" href="glib-The-Main-Event-Loop.html#G-PRIORITY-HIGH-IDLE:CAPS"><span class="type">G_PRIORITY_HIGH_IDLE</span></a> + 10 for resizing operations, and
<a class="link" href="glib-The-Main-Event-Loop.html#G-PRIORITY-HIGH-IDLE:CAPS"><span class="type">G_PRIORITY_HIGH_IDLE</span></a> + 20 for redrawing operations. (This is done to
ensure that any pending resizes are processed before any pending redraws,
so that widgets are not redrawn twice unnecessarily.)
