support for <code class="function">repr</code> Python function. Text representation will
include event type and a few most important event attributes,

for <code class="literal">gtk.gdk.BUTTON_PRESS</code> events. However, round-tripping
through <code class="literal">eval(repr(event))</code> is not possible: representation string
