 Only by maintaining a separate mapping between positions on the screen and
indices in the vector. This wouldn't be much faster if your vector contains
"small" objects (or pointers to large ones) though. It still can be a good
idea if you use the indices into this vector from other parts of your
program. In general I'd advise abstracting access to the data via methods
such as GetItemAtPosition() which would make it clear whether you access
the item by internal index or its position on screen and would allow you to
change the implementation later.
