+/* 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.

+/* A description:
+ *
+ * There are four possible operations on each bit in the destination word,
+ *
+ *	    1	2   3	4
+ *
+ *    0	    0	0   1	1
+ *    1	    0	1   0	1
+ *
+ * On examination of the reduced rop equation (dst = (dst & and) ^ xor),
+ * these four fall to reduced rops as follows:
+ *
+ *  and	    0	1   1	0
+ *  xor	    0	0   1	1
+ *
+ * or, (if 'and' is expensive) (dst = (dst | or) ^ xor)
+ *
+ *  or	    1	0   0	1
+ *  xor	    1	0   1	0
+ *
+ * The trouble with using this later equation is that trivial
+ * rasterop reduction is more difficult; some common rasterops
+ * use complicated expressions of xor/and instead of the simple
+ * ones while other common rasterops are not made any simpler:
+ *
+ * GXcopy:	*dst = ~xor		instead of  *dst = xor
+ * GXand:	*dst = *dst & ~or	instead of  *dst = *dst & and
+ * GXor:	*dst = *dst | or	instead of  *dst = *dst | xor
+ * GXxor:	*dst = *dst ^ xor	instead of  *dst = *dst ^ xor
+ *
+ * If you're really set on using this second mechanism, the changes
+ * are pretty simple.
+ *
+ * All that remains is to provide a mechanism for computing and/xor values
+ * based on the raster op and foreground value.
+ *
+ * The 16 rops fall as follows, with the associated reduced
+ * rop and/xor and or/xor values.  The values in parenthesis following the
+ * reduced values gives an equation using the source value for
+ * the reduced value, and is one of {0, src, ~src, 1} as appropriate.
+ *
+ *	clear		and		andReverse	copy
+ *     src  0	1	    0   1	    0	1	    0	1
+ *  dst	0   0	0	0   0   0	0   0	1	0   0	1
+ *	1   0	0	1   0   1	1   0	0	1   0	1
