old xfdesktop settings

[Brian J. Tarricone]

hey all-

danny asked this in #xfce-dev while i was asleep, and then /quit, and i 
think it's of general interest, so...

<+dannym> kelnos: I'm currently doing some debugging regarding xfdesktop 
image list prob...
<+dannym> kelnos: wondered what the difference between path, path_0, 
imagepath_0_0 is O_o

path and path_0 are old and don't do anything anymore.  the settings 
that currently do stuff are:

brightness_X_Y - image brightness (saturation)
color1_X_Y - first color
color2_X_Y - second color
colorstyle_X_Y - solid, vert/horiz gradient
imagepath_X_Y - filename of the currently selected image or image list
imagestyle_X_Y - tiled, stretched, centered, etc.
showdm - whether or not to load and show the desktop menu
showdmi - whether or not to show icons in the desktop menu
showwl - whether or not to show the window list
showwli - whether or not to show icons in the window list

where X is the xscreen number, and Y is the xinerama logical monitor 
number.  any other options are old and useless and can be safely removed.
