canvas item refactors

1.Supports tiled canvas with canvasSize, tileSize and canvasWindow
2.Supports different rendering targets: Canvas.Image and
  Canvas.FrameBufferObject by renderTarget property
3.Supports thread rendering when possible by threadRendering property.
4.Refactors QSGContext2D code, move some logic to
  QSGContext2DCommandBuffer,QSGContext2DTexture,QSGContext2DTile, etc
5.Updates/adds some canvas examples
6.Some improvements for context2d API
   6.1 drawImage() now loads image asynchoronously and draw images
       automatically when they are ready
   6.2 adds fillRule supports
   6.3 add svg path supports
   6.4 Pixel operations (getImageData/putImageData/createImageData)
       now have better performance by using V8 indexed array accessors
   6.5 Uses QTransform instead of QMatrix
   6.6 Gradients/patterns now are V8 values, not QObjects
   6.7 Supports measureText and TextMetrics interface
   6.8 Gives not support warnings for unimplemented functions
       (drawFocusRing,setCaretSelectionRect,caretBlinkRate)
   6.9 Better error handling, throw standard DOM exceptions according
       to the HTML5 context2d spec.
   6.10 Adds shear, resetTransform to matrix operations
   6.11 Adds roundedRect, ellipse, text to path operations
   6.12 Adds new features to CanvasImageData interface
      1) adds mirror() function
      2) adds filter() function, include the following filters:
          Threshold
          GrayScale
          Brightness
          Invert
          Blur
