Create a new layer.  Make it white.  Merge with your existing
transparent layer (that's what the checkerboard represents), or delete
the transparent layer.  Or leave it...

Activate that layer (in the 'layers' dialog).  Click around, you'll find
it.

Select the portion of the image you want.  Copy or cut it as you want.

> 2. move the selection into the checkerboard region without clipping.

Activate the new layer.  Paste.

Check that you don't have the "keep trans" (preserve transparency)
setting checked on that layer.

Layers rock.

    $ mogrify -rotate 90 foo.gif

...is another option.
