Width: Random starting offset over the width for each line, also used as constraint when "Limit Width" is active

Height: Random starting offset over the height for each line, also used as constraint when "Limit Height" is active

Limit Width: Limit width of lines to starting width, ignored if step size is larger than width

Limit Width: Limit height of lines to starting width, ignored if step size is larger than height

Length / Width / Height Step Growth: Set the minimum and maximum step size in each direction
