-Matrix Multiplication for rotating pieces.
-
-Each piece (shape) contains a Mat4 containing a representation of it's shape.
-For example:
-
-```
-0 1 0 0
-0 1 0 0
-0 1 0 0
-0 1 0 0
-```
-
-This is the classic `line` piece.
-
-And here it is on it's `up` side
-
-```
-0 0 0 0
-1 1 1 1
-0 0 0 0
-0 0 0 0
-```
-
-And here is the `t` piece
-
-```
-0 1 0
-1 1 1
-0 0 0
-```
-
-A matrix multiplication is applied to this Mat6 to achieve a piece rotation.
-
-When that matrix is updated, the 4 blocks parented to the shape are moved to reflect this new shape.
-
-This matrix also allows us to do checks to see if any of the blocks in the shape would intersect with another piece on the board.
-We can also check if a piece would go out of bounds during a move or rotation.
-
-We can use this to "plan -> validate -> commit" changes based on user input.
-
-Question: How the fuck do matrix multiplications work??
