-/* 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.
