Gets the color of a pixel at a specific position in the image.
Valid x and y values start at 0 and go up to image width and height minus 1. Non-integer values are floored.
In versions prior to 11.0, color component values were within the range of 0 to 255 instead of 0 to 1.

When the mouse is clicked, reads the red, green, and blue value of the pixel under the mouse and uses it as the background color.
