Sizes of widgets are shown as their size before DPI scaling is applied after changing ScreenSize

If the user sets the screen size to iPhone 4s (640 x 960) A widget that is "Fullscreen" will be roughly 1080 by 1620 in size (as reported by the details panel). This is the size before the DPI scaling is applied (DPI Scale = .59). The expected size that is reported would be 640 x 960.

1. Open the editor
2. Create a new widget blueprint
3. Set the screen size to the iphone 4s
4. Place a border into the canvas panel
5. Set the anchor to fullscreen
6. Set the position and size offsets to 0.0
7. Change the Anchor to the top left (There should now be a border that is the exact size of the canvas)
8. Notice that the size of the canvas is around 1080 by 1620 when the size on the bottom left of the graph reads 640 by 960

Expected: The size of the widget would read when filling the canvas that of the current dimensions depicted in the bottom left of the graph

Result: The size of the widget is the size the widget would have been be for the DPI scaling is applied.
