Gallery3D: Add depth component to icon animation
When the Gallery application positions the thumbnails
in a GridView, they are placed in the same z-plane.
When a configuration change occurs the icons present
a z-fighting visual artifact.
This patch adds a z component to the thumbnails when they are
animated as to mitigate this effect. This is specially
noticeable in a GPU architecture using deferred rendering.
