The shape of the brick you are trying to push through a hole is
analysed (inferred) by the universe from the brick's overall
properties, while the hole certainly can be said to expect a certain
shape of block.

The actual universe might very well do pixel-based collision, not
something as elaborate as what I described, though. YMMV.
