<pre>/* call-seq:
* window.setIcon( width, height, pixels )
*
* Change the window's icon.
*
* pixels must be an array of width x height pixels in 32-bits RGBA format. In the ruby binding the array will be
* flattened so you can have array's up to 3 dimensions(or more) to represent each pixel component. The size of the
* array will be assumed to be width * height * 4.
*
* The OS default icon is used by default.
*
* Usage example:
* pixels = [
* [[255, 0, 0, 255], [0, 0, 255, 255]],
* [[0, 255, 0, 255], [0, 0, 0, 255]]
* ]
*
* window.setIcon( 2, 2, pixels )
