-/* single-pixel lines on a color frame buffer
-
-   NON-SLOPED LINES
-   horizontal lines are always drawn left to right; we have to
-move the endpoints right by one after they're swapped.
-   horizontal lines will be confined to a single band of a
-region.  the code finds that band (giving up if the lower
-bound of the band is above the line we're drawing); then it
-finds the first box in that band that contains part of the
-line.  we clip the line to subsequent boxes in that band.
-   vertical lines are always drawn top to bottom (y-increasing.)
-this requires adding one to the y-coordinate of each endpoint
-after swapping.
-
-   SLOPED LINES
-   when clipping a sloped line, we bring the second point inside
-the clipping box, rather than one beyond it, and then add 1 to
-the length of the line before drawing it.  this lets us use
-the same box for finding the outcodes for both endpoints.  since
-the equation for clipping the second endpoint to an edge gives us
-1 beyond the edge, we then have to move the point towards the
-first point by one step on the major axis.
-   eventually, there will be a diagram here to explain what's going
-on.  the method uses Cohen-Sutherland outcodes to determine
-outsideness, and a method similar to Pike's layers for doing the
-actual clipping.
