%SHOW Display axes of affine mappings as images, if available
%
%	SHOW(W,N)
%
% If W is a affine mapping operating in a space defined by images\
% (i.e. each object in the space is an image) and the image information
% is properly stored in W (imageheight in W.p) or given in N, then
% the images corresponding to the axes defined by W are displayed.
