Blitter object

A Bob (contraction of Blitter object) was a graphical element (GEL) first used by the Amiga computer. Bobs were hardware sprite-like objects, movable on the screen with the help of the blitter coprocessor. An AnimComp added animation to a Bob and an AnimOb grouped AnimComps together and assigned them velocity and acceleration.
