%
%  A description of each parameter follows:
%
%    o display: Specifies a connection to an X server;  returned from
%      XOpenDisplay.
%
%    o resource_info: Specifies a pointer to a X11 XResourceInfo structure.
%
%    o argv: Specifies the application's argument list.
%
%    o argc: Specifies the number of arguments.
%
%    o images: the image list.
