It would be really good to have such a feature as I think it would
make browsing images in image-dired's thumbnail buffer (display some
large images there and use SPC and DEL to go back and forth to see
what I mean) much quicker. At least I guess it would be quicker to do
this natively inside Emacs than using convert to scale the image as we
do now. I assume the image libraries that Emacs use support scaling in
some way. When on the subject of images, it would be really neat if we
had built-in EXIF (et al) support as well, although I understand if
people do not think it fits well in Emacs.
