Window glow with color


Visual Studio RC and Office 2013 Preview has used a glowing effect on their windows. Visual Studio especially has a colored glowing effect, and the color changes to orange in debugging mode.
Spy++ reveals that this is achieved by creating four extra windows, one for each side of the window. This is likely done (instead of one big window) for performance.
This is a very cool effect compared to the native Aero shadow, which is more suitable for round-cornered Aero borders.
Should we implement this?
