Add option to set window background color

This window background color is different than window.clear(color)
because this window color is the background color if the window itself,
which means if there is a delay between creating the window and the
first frame display then the window background color is black,
but if window color is set then that color will be displayed instead.
Normally you want to set the window background color to the same
color as the color you use in window.clear(color).
