Bug Description

Semi-multitouch devices provide the number of touches and a bounding box containing the touches on the surface. This allows for recognition of pan and pinch gestures, but rotation gestures are impossible to determine. Grail needs to prevent rotation gestures from being emitted for these devices.

This been a little discussion around this bug. I want to wait before we push into the package. It seemed like there was consensus on this fix, and now there might not be. I will retarget the bug fix to beta 2.

A dissention came up, but the argument seemed to need some gestation :). I'm calling open season on this patch, but unless a meaningful argument against it is raised this will be pushed into natty after the beta 1 release.

Why is this important if semi-mt devices are not even supported yet?

I suggest we let this one stay in trunk together with all the other major but less critical changes, as we discussed.
