That's particularly interesting, because I wrote an XFCE theme in order to get:
- 1 pixel wide window borders (left/right/bottom)
- big thick corners to grab with the mouse
- and an aesthetically pleasing (to me) titlebar that is high contrast when not the focus (because that's when you're looking for a new window to select) and medium contrast when it is the focus (because most of the time you already know what you're typing into).
