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.

ca60a5a6cf convert the function to a qgraphicswidget:
sceneeventfilter appears to eat events always and in this way i can
remove elements from dragHandles when they get deleted

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

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.

a4d591e6fd ensureRectVisible() a rect in internal widget coordinates will cause an
animated scroll until the rect becomes visible
it should not collide with kinetic scroll since the anim is stopped as
soon as amouse or wheel event is triggered

974df6773a Adding a kinetic scrolling class and using it in plasma::ScrollWidget.
ATM, it uses timers to do the animation, the idea is to use factory pattern
and implement the animation with QProperyAnimation too (using Qt 4.6).
