I have implemented block (rectangle) highlighting some years ago, but
I'm not using the point-mark system. I have a different system of marks
(characters mark - same as Emacs original point-mark, line marks that
marks whole lines, and block marks - opposite corners of rectangle).
I have 3 commands for marking, 1 for each type. The highlighting is
done according to the mark type.

I find it very useful.
