Scaling is good, but it's difficult to know which size to use.
Worse, the same image might need to be displayed at different sizes in
different windows, since the same text may be rendered with different
font size in different windows.

IOW, I think this requires support on the C side, e.g. to specify the
image height as a multiple of the line height or as a multiple of the
"current font"'s height.
