           Summary: [Android] The touchmove delta used in
                    basic-single-touch-events.html is too small for
                    Android
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Android

          Priority: P2
         Component: Tools / Tests

Android is failing the basic-single-touch-events test due to an optimisation in
the Android framework that does not forward touch events to WebCore if they are
a small move. Currently the delta used in the singleTouchSequence function
in basic-single-touch-events (10, 10) -> (20, 15) falls within the scope of the
optimisation and so we fail the test as the touch event is not sent to WebCore.
I'd like to propose increasing this delta so that the test passes on Android. 

Proposed patch to follow.
