Comment 2 for bug 170291

What is the problem with tiling an image and editing its
shape? It fulfills all cropping needs and more, as it allows
non-rectangular cropping too. If something does not work as
expected file a bug. A way to physically crop a bitmap (as
opposed to masking out parts of it as a tile, or later via
an SVG mask) may be useful only for reducing file size and
only after we add image embedding. It's definitely not a
close perspective.
