&gt; &gt; +    void pressureDidChange(float force, int stage);
&gt; 
&gt; Some indication of what kind of pressure or what you're talking about at all
&gt; might be good :D mousePressureDidChange? No idea.
&gt; 
&gt; Also why is it pressure and force?
&gt; </span >

The NSResponder method uses the term &quot;pressure,&quot; which is why I used it here. Maybe we shouldn't let that spread into our code? But for the time being I used it to keep it more directly tied to the NSResponder method of that name.

&gt; &gt; +    if (m_lastPressureEventForceStage == 1 &amp;&amp; stage == 2)
&gt; 
&gt; Isn't the negativity of stageTransition how you're supposed to figure out
&gt; which direction you're going? Can we totally avoid caching the old one in
&gt; that case?</span >

stageTransition is not consistent for this purpose as far as I can tell.</pre>
