To run the spring animation, IconGrid uses the transformed position and size of the icons. This works okay when IconGridLayout doesn't need to update the icon sizes, but looks bad when IconGridLayout selects a different icon size. Wait for the icon sizes to be recalculated, and the icons beallocated, before running the spring animation. If no icon size update is pending, run the spring animation directly.
