Graphics lib ios

Notes one graphics lib for iOS:

• the truth is that you need a decorator style system to avoid too many concrete classes

• just clean up v1 when porting to iOS

• your new code that can reach protocol from shallow super type is cool

• Decorator isn't too bad for value types as you can always copy vars to a new instance with less decoration if an instance gets too much decoration

Wants:

• addSubView(Graphic())//draw on init

• init colors via: .blue,.red,

• init gradients via: .redBlue

• init gradients via: NSColor.blue.to(.red)//gradient

• init RectGraphic via: CGRect(0,0,100,100).graphic.fill(.red).stroke(.blue,10)

• init CircGraphic via: CGEllipse(0,0,100,100).graphic

• init RoundRectGraphic via: CGRect(0,0,100,100).graphic.fillet(20)

• init PolyLineGraphic via: [CGPoint(0,0),CGPoint(50,50)].graphic.stroke(.redOrange,4)

• init PathGraphic via: Path([.mt,.lt],[0,0,40,40]).graphic.stroke(.blue,10)

• init DropShadow via: CGRect(100,100).fill(.orange).dropShadow()//Blue rect with default dropshadow applied
