I don't see how. Absolutely not. Emacs moves point out of images.
Without stopping points, point will not remain inside of the image
anywhere. And I certainly can't draw a cursor box over a selected
area of an image. Or have mouse highlighting over a selected area.
I am still thinking about Kim's proposal (horizontal slices with
vertical subslices) with regard to use under preview-latex. It would
certainly cater for pretty much every important application I
currently have in mind.
