Comment 10 for bug 823640

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.
