pywinauto coordinates
<p>when I was testing its examples, I was confused about its coordinates.</p>

<p>In the mspaint.py in Examples/</p>

<pre><code>#make sure the pencil tool is selected

pwin.Tools2.Click(coords = (91, 16))
</code></pre>

<p>The Tools2 references the painting tools pannel. But I don't know what the (91,16) means,
the notes says “make sure the pencil tool is selected", But It seems that (91,16) is not point to the pencil whether from left-top or right-top window coordinate.</p>

<p>And if I manually select the brush tool, running the above code would not select the pencil,
so apparently it is not correct.</p>

<p>another confusing thing is that when I run the following code</p>

<pre><code>  app.start_(ur"mspaint.exe")
        pwin=app.window_(title_re = ".*-Paint")
        pwin.print_control_identifiers()
</code></pre>

<p>the console shows that</p>

<pre><code>AfxControlBar42u - 'Tools' (L4,T50,R4,B334)
</code></pre>

<p>What does (L4,T50,R4,B334) means? if left-top is (4,50), and the right-bottom is (4,334)
It apparently is not a rectangle.</p>

<p>Does anyone can help me?
Thank you.</p>
