T-Spins (and other block spins)

[docquantum]

In classic mode, a place is able to rotate a block before it's placed, even if it that rotation would cause collision. Subsequently, a fast set of key inputs would allow for a player to quickly rotate and move a block, such as a T block, to place it within a set of holes that would fit the block, even if the entrance would normally not allow for such a thing to happen.
