Does that imply that slicing is not only applicable to images?
Anyway, I have been wondering about how to make slicing an image
property while being able to reuse the image for several slices.
Making this a separate property of course solves that concern.
The effect would presumably be that only the selected slice of the
image gets displayed, right? And if the current line height exceeds
that of slices in consecutive rows, then there would be white space
between them, right? Does anybody know offhand whether one can
_reduce_ the linespacing to "tight" for a given interval?
It probably will not be "crucial" though.
