Keep movement steady on any screen while drawing it smoothly

If the game world moves in tiny equal steps but the screen refreshes at a different rhythm, characters shimmer or stutter, and one slow frame can make the game fall further and further behind. Here is how to avoid both problems.

Why this works

The same input should give the same result on any machine, which needs steps of one fixed size, while a screen shows frames at its own rhythm. Running whole steps and drawing a blend between the last two gives both: repeatable rules and no stutter.

When not to use it

Don't use it for a simple game with no real physics, like a card game or a menu, where it only adds delay and work, or when you need the very newest position in a fast shooter. Draw the latest state directly there.
