A question about print preview border color

[davidh]

Is there any particular reason why the general border of the print preview is grayish instead of white like it is in PWP7?
It can be confusing when the print preview looks differently from the output preview. It is especially deceptive when the border of the print preview comes out a bit darker then light shades in the image alongside the border.
If someone needs the print preview border color other then white, would it make sense to set also the color of this border by the current Border Color control in Preferences?

It is to distinguish the margins from the other unused space around the image.
