posted to net.sources.mac is C source to surround a line with a region defined
as a rectangle 2 pixels wider on each side.

A few notes, in my original reply to the question, I assumed you could
use "improper" rectangles.  This is not the case.
The routine probably does not do what the original question wants, what does
what it asks.  A rectangle is defined so that 2 opposite corners are the
endpoints of a line, then expands the rect 2 pixels on a side and makes it
a Quickdraw region.   If that region is framed, it draws the frame INSIDE
the rectangle definition, making it tangent to the line, instead of disjoint.
