I originally did this to make things easier (it's very hard to get
pixel-perfect positioning with the mouse), but if you want to disable it
you just need to remove some '&' statements from the bitmap grabbing
function in grabber.c.

Alternatively, download the work-in-progress version of Allegro from
http://www.talula.demon.co.uk/allegro/. This contains an improved
grabber that lets you specify any snap size you like, or turn the grid
off altogether.
