PDF/image viewers provide a menu item "Fit Image Width".
It's very useful to read long text on images. Therefore
here is the same for the image-mode menu:

To match the similar entry above, this should say "Fit Image to Window
Width", which is not only consistent but also clearer and grammatical.
> + :help "Resize image to the width of the current window."]
Ditto, to match the similar entry above, this should say "Scale image
down to match the window width".

Agreed. This title was copied from other programs,
but should match the existing style.
OTOH, I'm worried that both 'image-transform-fit-to-width'
and 'image-transform-fit-to-height' were declared obsolete.
So I'm not going to revive them.
Instead I'll implement a more useful item
"Fill Image to Window" that will fill the image
as much as possible to the window without leaving
any glaring empty space. This means applying
either fit-to-width to vertical images (portrait orientation),
or fit-to-height to horizontal images (landscape orientation).

This works nicely:

One new command is better than old two commands,
so now pushed to master.
