Sorry, I don't understand it, why 10 pixels? In my case `auto' creates very
large images (i.e. (frame-char-width) ==> 30), so scaling factor is 3.
This creates very large images by default.

I know I can set `image-scaling-factor` to whatever I need.  However I want
to understand the default behaviour decision, why 10 pixels is considered
as "typical character" width?

I think, by default `create-image' should create images that look good when
inserted into buffer, that is *not* what I get by default.
