This method allow to set a background color to the browser. This color is only useful if the first DFrame does not recover all the surface of the browser (position different from [0, 0, 100, 100]).
If the setBackgroundColor method has not been used when the first DFrame loads the background color will automatically be set as the same as the background color of this first DFrame.
