bug#15502: 24.3.50; image-transform-* do nothing

[Michael Heerdegen]

Hello,

built Emacs myself from trunk, it's up to date.  configure says:

,----------------------------------------------------------------------
| checking for Wand >= 6.2.8 Wand != 6.8.2... yes\
|   CFLAGS='-fopenmp -I/usr/include/ImageMagick\
|   ' LIBS='-lMagickWand -lMagickCore  '
| checking for MagickExportImagePixels... yes
| checking for MagickMergeImageLayers... yes
| 
| ...
| 
| Does Emacs use imagemagick?                             yes
`----------------------------------------------------------------------

But in emacs -Q as well as with my private setup, when I view an image
with `image-mode', M-x image-transform-* all do nothing - just nothing
happens, the image looks like before, no error message.  I expected it
to work (i.e., to display the transformed image).

I `edebug'ed `image-toggle-display-image' - everything seems to be fine
from the lisp side.


Thanks,

Michael
