Option to offset the password window
Would be useful to have options x-offset and y-offset, values could be pixels from the initial position. positive numbers for down and right, negative for left and up. A use case would be if the set background image has some prominent feature in the center of the image.
example, window appears 10px to the left and 25px below where it would normally appear:
x-offset = -10px
y-offset = 25px
