Title: Support padding frames.

This supports padding on either side of the frame:
- Left padding of 10 moves the framed image 10 pixels to
the left. This allows for thick frames that don't obscure
any image content.
- Left padding of -10 moves the frame 10 pixels to the left.
This lets the frame sit inside the framed image.
