2.5

Made sliders behave correct in SpaceGraph and SpaceAction.
- no slider draw when all is visible
- sliders update correct when visibility changes.

Still an issue here to tackle; view2d->tot is used incorrect...
it's set on window size now (??), it should be the boundbox of 
the entire contents. That allows correct slider draws and ops
like 'view home'.
Will poke Joshua tomorrow. :)
