Pushed by filipf into branch 'fix-illegible-tooltips'. oxygen: Fix illegible tooltips in Oxygen desktop theme Oxygen currently renders dark tooltips and dark text. That results in illegible icons. This patch switches it around so that tooltips are dark and the text is white, what should be expected of a dark theme. The rest of the color values are taken from Window because it has the same white text on dark background structure.
