It almost always scales the image (either up or down), so that
the image has
width=0.8\textwidth,height=0.8\textheight,keepaspectratio 

It would be nice if one could say
maxwidth=\textwidth,maxheight=\textheight,minwidth=3cm,minheight=3cm,keepaspectratio
and then the image would either be scaled up or down or not at
all depending on the image size.
