I just pulled the latest Emacs master and compiled it. I did not install
it though, but run

$ ./src/emacs

I opened a tex file with contained via includegraphics a png file I then
started  iimage-mode

In fact the png was displayed in the buffer as expected.


However I could not detect any change to the version I currently
installed which is 

GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2018-04-26

emacs-repository-version is a variable defined in ‘version.el’.
Its value is "1d75604eaded6a8482d28d57bc8e6a4d99d5caee"


So how am I supposed to do the rescaling?

Thanks and regards
