Also it would be useful for Meego netbooks devices with Gtk environment...

Attachment: Simple compress with 0 timer

This is the only way I found how to compress Qt motion and pinch events...
GTK compress way does not work on Qt.

This help us to avoid too many motion events processing.

Looks reasonable, but instead of a zero-length timer, it might be simpler and work just as well to use a simple XPCOM event instead ... NS_DispatchToMainThread etc.

Attachment: Updated, filter motion and pinch events

1) Use DispatchtoMainThread for filtering.
2) Minor code cleanup.
3) calculate distance touchPoint and center point.
