Extension DrawNodeEx ‐ a new kind of sprite class (*experimental phase*)

[aismann]

FIRST: Because of possible side effects with class DrawNode the extension DrawNodeEx aka DrawNode v2 is still in the experimental phase and may encounter bugs or stability or compatibility issues when used.

DrawNodeEx is not only a class for drawing primitives, it's more:

• It's DrawNode v2
• It's a kind of sprite created from drawing primitives!

Features:

• Individual line width

  setDNLineWidth();
  getDNLineWidth();
  
  Default value: `1.0f`

• Scale/Rotation/Position

  Scale:
  setDNScale()
  setDNScaleX()
  setDNScaleY()
  Rotation:
  setDNRotation()
  getDNRotation()
  setDNCenter()
  getDNCenter()
  Position:
  setDNPosition()
  getDNPosition()

• general

  ensureDNValues()
  restoreDNValues()
  resetDNValues()

• Planed APIs:

  enableDNTransform()
  getDNSprite()
  explodeDNSprite()
  transformDNSprite()
  morphDNSprite()
  createAnimDNSprite()

• [x] Add initial DrawNode v2 as extension DrawNodeEx to axmol as experimental

• [x] DrawNode API compatible

• [x] Add individual line width for drawing primitives

• [x] Scale drawing primitives without changing the individual line width.

• [x] Rotate drawing primitives around a customized center

• Useful tests

  • [ ] funktional
  • [ ] performance/robustness
  • [ ] compare DrawNode vs DrawNode v2

• [ ] Code Cleanup

  • [ ] Remove/Add some comments
  • [ ] Reduce compiler warnings

• [ ] Documentation, Wiki

  • [ ] Info about AX_TRANSPARENT

New drawMethods:

• drawStar()
• drawSolidStar()

• suggestion: DrawNodeExt ==> DrawNodeEx
• question: move it to extensions/DrawNodeEx folder?

No problem. I will move and rename it
