Checking the position means you will not get smooth movement.
Assume the mouse is warped to x = 100, and the user moves the mouse 10
pixel to the right, then 10 pixel to the left. So Allegro's event queue
contains movement events like this:
event 1: e.x = 110; e.dx = 10;
event 2: e.x = 100; e.dx = -10;
In your game, you now ignore the second event completely, as if the user
never moved the mouse to the left. Players of the game really will hate
you :P
