Crashes when tapping with more fingers

[tacone]

WorkspaceView crashes when tapping very fast one child window.

To reproduce tap the screen fast using at least two o three fingers, (first with the index finger, then with the second finger, then with the third finger).

I haven't been able to reproduce the issue with just 1 finger, and with two it is difficult to reproduce (at least on a fast smartphone). With three fingers is pretty easy though.

Hello, My suggestion for quick fix for this one is to add: "if ( pointerIndex == -1 ) return;" at the beginning of handleScrollMove and handleInterceptMove.

Bug happens because findPointerIndex can sometimes return "-1". It seems to work fine with this fix.
