10   Based on the helper callbacks implemented by <em class="parameter"><code>connector</code></em> try to detect all
11   valid modes.  Modes will first be added to the connector's probed_modes list,
12   then culled (based on validity and the <em class="parameter"><code>maxX</code></em>, <em class="parameter"><code>maxY</code></em> parameters) and put into
13   the normal modes list.
