Re: about GdkColor

[Noah Levitt <nlevitt columbia edu>]

The api docs say 

 guint32 pixel For allocated colors, the value used to draw
               this color on the screen.

When the color is allocated (e.g. with gdk_rgb_find_color)
this field is filled in. I don't think you have to worry
about initializing it to anything in particular).
