2.5: Buttons View 

* When resizing the window, the top position is now preserved,
  instead of the center position.
* Fix zoom level not being preserved in various cases, when
  changing both with and height. This replaces some earlier code
  which did this at screen level but wasn't very reliable.
* Different tabs now each preserve their own scroll.
* When switching between tabs, it now scrolls to show as many
  buttons as possible, instead of possibly showing empty space.
  There is a trade-off here between doing that keeping the
  buttons in the same place, no ideal solution exists I think.
* Change zooming in/out to be symmetric, for example doing
  numpad + then - did not give the original zoom level back.
* Added some calls to avoid hanging tooltips when manipulating
  the view.

Internals:
* Added V2D_KEEPOFS_X and V2D_KEEPOFS_Y to keep the top/bottom
  rather than the center.
* Renamed V2D_KEEPZOOM to V2D_LIMITZOOM (seems more appropriate),
  and make V2D_KEEPZOOM preserve the zoom level.
