2f8e70b7ab make the webview widget use scrollwidget for flicking 
still some issues to fix, but most of the behaviour is ported.

76d131a501 experiment two behavioural changes: 
- don't flick when the contents are smaller than the view (or flick only for the axis where the contents are bigger)
- still pass mouse moves to childrens so they can initiate drags (useful? annoying? still to be found, but necessary for netbook sal to work at the moment)

82702e7043 Improve kinetic scrolling on ScrollWidget 
As previously discussed with this approach we can actually properly intercept events from child items. Furthermore now we properly "steal" events which cause a flick (it's important for child items to properly act on mouseReleaseEvents and not on mousePressEvents as some like to do, since it's the release events that cause a flick) so items don't get clicks when flicked. The physics and especially the overshoot behavior is a lot better in this code as well.

fdae3f0d59 This patch forward the "stateChanged" signal emitted from the private kinetic scroll animation all the way to Plasma::ScrollWidget, which then forwards this signal to its childs. This enables an object which derives from Plasma::ScrollWidget to know the kinetic scrolling animation state.

the animator creates a kineticscroll and associates it with the widget.
in this way we can use kineticscroll outside of libplasma with a single
call.

38884ccd1a now the api is similar to what webkit offers and horizontal and vertical 
scroll is done in pixels and in a single pass.                                          
we have 3 properties in widgets that wants to support scroll:
scrollPosition
viewportGeometry
constentsSize

3d33d3f28f Factoring the ratio of widget/viewport size when doing the

This will help to have a proper scrolling in cases that the
viewport is several times smaller than the widget size.

99cdc241c3 Making kinetic scrolling class generic. 
The current design uses 3 properties to calculate movement (horizontal/vertical 
position and the viewport size) being up to the client class (e.g. ScrollWidget)
move its widgets when the position property changed.

It will allow to reuse the kinetic scrolling class with other plasmoids.
