The file that needs this the most is wid-edit.el.  When the cursor type is
`bar', typing TAB repeatedly on a column of checkboxes for face attributes
in the face customization buffer has no visual feedback at all.  I propose
the patch below to add 1-pixel margin around checkbox images.

Another place where I noticed this problem is thumbnail packages.
This will be fixed soon separately.
