Martin Gräßlin 302271ce97 [kwin] Client supports an X property for color scheme
The X property _KDE_NET_WM_COLOR_SCHEME can be set on a window and
specifies the absolute path to a .color file describing the color
scheme of the managed client.

The Client reads this property and creates a QPalette from it. If
the property is not set or the value is incorrect, the Client uses
KWin's default palette.

The idea behind this property is to allow an application with a
custom color scheme to tell KWin which color scheme the window
decoration should use. So that the window looks as a solid pattern
again.
