It's actually the other way around, Shift+click when building an object disables the "snap to grid" effect and enables it when dropping the item (Shift+r-click).
You see a masterful engraving by Blaze. On it is Blaze, bears, boars, and foxes. Blaze is striking down the bears. The boars are screaming. The foxes are in a fetal position. The image relates to the return of Blaze in the late winter of 2009.
