centeredScaling: Define if object scaling should be centered (true). Default = false.
centeredRotation: Define if object rotates around center (true) or around origin (originX/originY) point (false). Default = false.
Pressed altKey negates the behavior.
Fixed "enum" notation
`fabric.Object.setGradient` is now chainable
Doc additions
Add `fabric.Object.setPatternFill`unit test
Add chainable tests to some methods
[BACK_INCOMPAT] `fabric.BaseBrush`shadow properties are combined into one property => `fabric.BaseBrush.shadow`(shadowColor, shadowBlur, shadowOffsetX, shadowOffsetY no longer exist)
Removed fabric.Text.getText method => is generated with `fabric.util.createAccessors`
`fabric.Shadow` can now initialized with string or object (e.g. '10px 10px 5px rgb(0,0,255)', 'rgb(0,0,255) 10px 10px 5px', {color: 'gb(0,0,255)', offsetX: 10, offsetY: 10, blur: 5})
`fabric.Shadow.getShadow`to get css3 declaration of shadow (String)
`fabric.Object.set('shadow', value)`is now the same as `fabric.Shadow.setShadow(value)`
Add unit tests
sendBackward/bringForward functions now take an additional parameter
`intersecting` (boolean).
If `true`, send object behind/in front of next intersecting object.
If `false` (default), send object one level down/up without checking for
intersection.
