Omega race uses a digital vector generator (DVG). It's very similar to
the original Atari DVG used in Asteroids. It doesn't draw smooth lines,
but instead draws a series of dots on a 1024x768 array. The staircase
results are similar to a 1024x768 raster monitor -- though better than a
raster, because the dots are connected, while on a raster monitor the
scan lines don't always overlap, leaving gaps in the vectors. Vector
monitors are also much brighter.

The ZVG uses an analog vector generator (a much improved version of the
Cinematronics vector generator), a smooth analog voltage is used to
connect the to endpoints of a vector, so there are no stair stepping
effects.

It makes for much cleaner vectors than the DVG of the Omega race, but on
the other hand it's not a perfect emulation of the jagged vectors of a DVG.
