I don't like the hardwired factor of 4: after all, nothing like this
will be applied if you use large fonts. I think we should try to make
characters and images behave comparably. Having a general size
limitation variable available for block cursors, whether we are
talking images or characters, would be more consistent.
This size limitation could be specified as either float (multiple of
default font size) or integer (pixels? Or 10ths of points?).
Of course, if an image has no transparency, we probably need to use a
box cursor, anyway.
