I followed John's 'peek' addition. I have 2 monitors, the second one has a
125% magnification. Windows 10.
Rectangle2D [minX=0.0, minY=0.0, maxX=1920.0, maxY=1080.0, width=1920.0,
height=1080.0]
Rectangle2D [minX=1920.0, minY=0.0, maxX=3456.0, maxY=864.0, width=1536.0,
height=864.0]
The buttons are 3456.0 and 2688.0.
The first one moved the stage to the far right of the second monitor, 76px
from the right of the stage to the screen's edge.
The second one moved the stage to the center-right of the second monitor,
576px from the right of the stage to the screen's edge.
