Title: Remove MozMousePixelScroll handler because we no longer need it.

Horizontal and vertical scrolling now work on the same scrollbox, so the built-in behavior works just fine!

Before we had the amazing position:sticky tree columns, we had nested scrollboxes, one for horizontal and one for vertical scrolling.
