Glowing Buttons

Today Cornelius added support for drawing titlebar button images outside the window on hover, which means cool stuff like glowing buttons is now possible... (In fact, it draws two images, the normal button and a glow overlay)

Edit: the forum post with patches is here

He says:

implemented button glow (for the hovered buttons of the active window) in cgwd. Here is the patch. The glow overlay image should consist of 7 images of same size for the 7 button types.
....
To enable glow:
Add this line to the end of the [buttons] section of your theme.ini file (mine is at /.compiz/cgwd):
glow=your-glow-image.png

And here is his screenshot of the glowing buttons




The actual glow.png should look like this
