% XMakeImageMSBFirst() initializes the pixel data of an X11 Image. The X
% image pixels are copied in most-significant bit and byte first order. The

% general cases, many special cases are found here to help speed up the image
% conversion.
%
% The format of the XMakeImageMSBFirst method is:
%
% XMakeImageMSBFirst(resource_info,window,image,ximage,matte_image)
%
% A description of each parameter follows:
%
% o resource_info: Specifies a pointer to a X11 XResourceInfo structure.
%
% o window: Specifies a pointer to a XWindowInfo structure.
%
% o image: the image.
%
% o ximage: Specifies a pointer to a XImage structure; returned from
% XCreateImage.
%
% o matte_image: Specifies a pointer to a XImage structure; returned from
% XCreateImage.
