fixed the gesture module to not break with 4.0 #6491;
fix(fabric.IText): copy style in non full mode when typing text #6454;
feat(fabric.Controls) expose the extra utils for control handling.
Breaking: rename fabric.controlHandlers and fabric.controlRenderers to fabric.controlsUtils.
fix(fabric.Image): ISSUE-6397 modify crossOrigin behaviour for setSrc #6414;
Breaking: fabric.Image.setCrossOrigin is gone. Having the property on the fabric.Image is misleading and brings to errors. crossOrigin is for loading/reloading only, and is mandatory to specify it each load.
Breaking: fabric.Control constructor does not accept anymore a position object, but 2 properties, x and y.
