white outline around the arrow on window operations buttons
To create the graphics, the visual designer needs a screenshots of the buttons the icons will be on (there are no
buttons as of now in nimbus implementation, but there should be in the future). Marek agreed to provide those
screenshots ... reassigning to him.
The white outline is necessary to maintain visibility on inverse color schemes.
Closing as WONTFIX.
