feat(): remove deprecated code from older versions

[asturur]

• removed Object.setShadow, and BaseBrush.setShadow. change rect.setShadow(options) to rect.set('shadow', new fabric.Shadow(options))
• removed Object.transformMatrix. If you still have transform matrix in your designs look at how fabric removes the transform matrix from svg and preserve visual correctness.
• removed object:selected event. use selection:created. In the callback you will still find target in the options, but also you will find selected with all the objects selected during that single event.
• removed Gradient.forObject. It wasn't that helpful. The new gradient options introduced in 3.4.0 make up for the missing method.
• removed Object and canvas clipTo. Use Object.clipPath;
• removed Canvas.loadFromDatalessJSON, it was just an alias for loadFromJSON
• removed observe, stopObserving, trigger from observable. Keep using on, off, fire.
• removed the Object.set ability to take a function as a value. Was rather strange to use.
• removed Object.setGradient. Change rect.setGradient(options) with rect.set('fill', new fabric.Gradient(otherOptions)). The options format is slightly different, but keeping 2 formats does not really make sense.
• removed Object.setPatternFill. Change rect.setPatternFill(options) to rect.set('fill', new fabric.Pattern(options));
• removed Object.setColor. Change rect.setColor(color) to rect.set('fill', color)
• removed fabric.util.customTransformMatrix. Use the replacement fabric.util.composeMatrix

Hi @asturur , I think this wiki page[1] is out of date, such as object:selected event was changed to selection:created, how about removing it or added some tip[2] on it?

That is a breaking change for v4.
I think i should remove the wiki pages, since i already have problem mantaining the fabricjs.com doc website.

Agreed!
