Hello!

At the moment there is no possibilities to load image as raw RGB data in
GNU Emacs, even if using nice 'imagemagick image type.

The problem is that with raw rgb format the filename hint is not enough for
imagemagick to correctly interpret blob data.  size and depth also must be
provided.

I created tiny patch, that adds this functionality

Thanks
