Comment:

 During the hack week, I ran right past this comment (extracted from
 MouseDefaults.js into Handler/MouseWheel.js) without paying any attention
 to it:

   // add the mouse position to the event because mozilla has a bug

   // with clientX and clientY (see
 https://bugzilla.mozilla.org/show_bug.cgi?id=352179)

   // getLonLatFromViewPortPx(e) returns wrong values

 Caching the mouse location on mouse move works around this -- in fact,
 this is what MouseDefaults used to do, only it's done in the MouseWheel
 handler now. Also fixed the math in Control.Navigation. See the attached
 patch.
