Make clear in the Export Options preview what the sprite boundaries are

[YYBartT]

The preview in the Export Options doesn't show the boundaries of the final sprite:

So you might export a sprite that looks like it will export okay in the Export Options but which will be cut off on (one of) the sides afterwards, which will become visible only after exporting, e.g. when opening the image (strip) or when adding the generated image(s) as a sprite.

If this could be added to the preview it'd prevent these unusable exports from being done (or at least provide a way to visualize that the sprite will be clipped).
