Cell represents a single cell containing LetterSegments

func NewCell 

func NewCell(topLeft, bottomRight [2]float64, segments []Segment, deathColors, paradoxColors [2]color.RGBA) *Cell

NewCell creates a new Cell. The color arguments take an array of two colors, the first is the background and the second is the foreground.

func (*Cell) Draw 

func (cell *Cell) Draw(gc *draw2dimg.GraphicContext) bool

Draw calls the Draw method for all of its segments for them to render onto it. The image is then rendered onto the main context.

func (cell *Cell) Height() float64

Height returns the cell's height

func (*Cell) Scale 

func (cell *Cell) Scale(factor float64)

Scale increases the size of the cell, keeping the centre the same
