MrEd has no concept of a background image for a frame.

But for a "cards.ss" table, use `make-background-region' to create a
region with a paint callback, and then add the region to the table. The
paint callback can use dc<%>'s `draw-bitmap' method to draw a bitmap,
or you can use any of the other dc<%> drawing methods.
