Color incompatibility of xpm loader with libXpm
Submitted by Andrey Panov
The patch from https://bugzilla.gnome.org/show_bug.cgi?id=678996 changed some color names from the traditional X11 color chart to the W3C standard. For example, the "green" color was changed. Read more information here: http://en.wikipedia.org/wiki/X11_color_names
Thus, some colors, displayed by the gdk-pixbuf xpm loader and the libXpm differ. It is reasonable to use the X11 colors (e.g. as defined in libXpm/rgbtab.h) for xpm-color-table.h.
