Some function in Vecci only work with perfect vectorlists. What makes a vectorlist perfect?
a perfect vectorlist is ordered
all vectors are drawn "full" with a pattern of 255
all vectors are connected with their natural order
all vectors face the "correct" direction
all vectors have a length smaller than 127/128 (depending on the sign)
Think of perfect vectorlists as a drawing you can make with a pencil, without ever taking the pencil off the paper.
These vectors can be exported to any of the supplied formats.
They are in general quite performant. They should not be longer than (about) twenty vectors (otherwise on a real vectrex they will "drift").
