v 1.1: I centered the titles, decreased the height of the window manager by 1 px, created a different appearance for the close-active button, and added different appearnces for the pressed buttons.

v 1.2: I've added shadows to the active and inactive title text, I've defined the colors of the title text directly in the window manager theme, I added shadows to all windows and the panels, menus are now transparent, windows are now transparent when they are being moved.

v 1.3: I've added the gtk theme based on Billy Cantrell's work.

v 1.4: I included Olivier Fourdan's suggestion for defining the XFWM4's color in the gtrkrc file, so the GTK theme will work better with other XFWM4 themes.

v 2.0: I fixed an error that Thunderbird was causing with this theme (a big thanks to kashirigi for pointing this problem out to me), and I've now made it so that the xfwm automatically uses whatever color is called for in the gtk theme.
