Hi Seb,

The function names have been mangled so it's clear they are ubuntu-
added.

What we saw with the scroll to zoom feature was an issue with what the
user expects. Only one of scrolling and pinching can occur at a time due
to the architecture of uTouch. If the user intends to perform a zoom,
but a scroll is triggered instead, they will see zooming behavior that
doesn't match what they expect. It makes the pinch to zoom feel quirky.
However, we changed the threshold values a bit in utouch-grail
yesterday, and it appears the new thresholds have helped this issue. The
uTouch stack seems to be more accurately differentiating between a
scroll and a pinch now. We have reverted the scroll-to-zoom change in
the debdiff.
