fix bouncing effect of selected card view

When card animation is enabled, the scale pivot changed dramatically
because card height is changed before/after browse transition without
animation.  There is much less bouncing in "card -> card navigation"
because pivotY is animated with card height animation.

The fix is to allow pivotY being at a fixed location regardless info
height.  Pivot values also need to be transfered to shadow container
since the actual scaling is done on shadow container.
