I thought this would be a handy tool, for example, when embedding images in
an S5 presentation (see for example
http://www.schestowitz.com/Research/Presentations/April_2005)
The text in principle adapts in size to accommodate the screen nicely, but
images do not. Using your 2-line simplistic trick, which quite frankly,
somebody must have deployed already, one would still need to add an element
to warp the image. So it can be a pain that's not trivial or quick to add.
