Displaying images with recent trunk

[Angelo Graziosi <angelo.graziosi@alice.it>]

I wonder if someone has tried to display imaged with trunk, say, after 
Aug 05, 2014.

For example try this:

1. emacs -Q

2. C-x C-f 
/usr/local/Emacs.app/share/icons/hicolor/128x128/apps/emacs.png. It 
looks OK.

3. Now on menu bar click 'Image' and then 'Fit Frame to image'. 
Question: How to revert (undo) this?

4. Click on menu bar 'Image' and then 'Fit to Window Height'

5. Click on menu bar 'Image' and then 'Fit to Window width'

Repeat 3., 4., 5. in different order... and with various files...

Sometimes (I have tried with several PNG and JPG files), 4. and 5. gives 
the same result, i.e. a deformed image (which does not maintain the 
aspect ratio). Is this by design?

Image one is reading a PDF document.. If one want to see the full page, 
the fitting to window height is the best thing to do.. then to read 
better one fits to the window width: this does not deform the document, 
one has only to scroll up/down to continue reading. If then one want to 
see newly the full page then the choice is to refit to the window 
height.. 3., 4. 5. above don't look reversible..

It seems one cannot to zoom.. so that the image cannot be visited as in 
trunk prior Aug 05...
