- *
- * Either generate the next value to OR in to a pixel or break out of this
- * while loop
- *
- * This macro is used when we're trying to generate all 2^n combinations of
- * bits in mask. What we're doing here is counting in binary, except that
- * the bits we use to count may not be contiguous. This macro will be
- * called 2^n times, returning a different value in bits each time. Then
- * it will cause us to break out of a surrounding loop. (It will always be
- * called from within a while loop.)
- * On call: mask is the value we want to find all the combinations for
- * base has 1 bit set where the least significant bit of mask is set
- *
- * For example,if mask is 01010, base should be 0010 and we count like this:
- * 00010 (see this isn't so hard),
- * then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
- * we add that to bits getting (0100 + 0100) =
- * 01000 for our next value.
- * then we add 0010 to get
- * 01010 and we're done (easy as 1, 2, 3)
