C backend

Let's start to write your program ...
main.nim

import hapticx

var
  app = newApp("My own app")
  scene = newHScene()
  canvas = newHCanvas()

scene.addChild(canvas)
canvas.drawRect(0, 0, 50, 50, WhiteClr)
canvas.drawRect(48, 48, 64, 64, RedClr)

app.main = scene
app.run()

Then, let's compile it!
