+ * PNG Extensions
+ *
+ * New private chunks that may be placed in PNG images.
+ *
+ *********************************************************************** */
+
+/**
+ * This chunk specifies how to split an image into segments for
+ * scaling.
+ *
+ * There are J horizontal and K vertical segments. These segments divide
+ * the image into J*K regions as follows (where J=4 and K=3):
+ *
+ * F0 S0 F1 S1
+ * +-----+----+------+-------+
+ * S2| 0 | 1 | 2 | 3 |
+ * +-----+----+------+-------+
+ * | | | | |
+ * | | | | |
+ * F2| 4 | 5 | 6 | 7 |
+ * | | | | |
+ * | | | | |
+ * +-----+----+------+-------+
+ * S3| 8 | 9 | 10 | 11 |
+ * +-----+----+------+-------+
+ *
+ * Each horizontal and vertical segment is considered to by either
+ * stretchable (marked by the Sx labels) or fixed (marked by the Fy
+ * labels), in the horizontal or vertical axis, respectively. In the
+ * above example, the first is horizontal segment (F0) is fixed, the
+ * next is stretchable and then they continue to alternate. Note that
+ * the segment list for each axis can begin or end with a stretchable
+ * or fixed segment.
+ *
+ * The relative sizes of the stretchy segments indicates the relative
+ * amount of stretchiness of the regions bordered by the segments. For
+ * example, regions 3, 7 and 11 above will take up more horizontal space
+ * than regions 1, 5 and 9 since the horizontal segment associated with
+ * the first set of regions is larger than the other set of regions. The
+ * ratios of the amount of horizontal (or vertical) space taken by any
+ * two stretchable slices is exactly the ratio of their corresponding
+ * segment lengths.
+ *
+ * xDivs and yDivs point to arrays of horizontal and vertical pixel
+ * indices. The first pair of Divs (in either array) indicate the
+ * starting and ending points of the first stretchable segment in that
+ * axis. The next pair specifies the next stretchable segment, etc. So
+ * in the above example xDiv[0] and xDiv[1] specify the horizontal
+ * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and
+ * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that
+ * the leftmost slices always start at x=0 and the rightmost slices
+ * always end at the end of the image. So, for example, the regions 0,
+ * 4 and 8 (which are fixed along the X axis) start at x value 0 and
+ * go to xDiv[0] and slices 2, 6 and 10 start at xDiv[1] and end at
+ * xDiv[2].
+ *
+ * The array pointed to by the colors field lists contains hints for
+ * each of the regions. They are ordered according left-to-right and
+ * top-to-bottom as indicated above. For each segment that is a solid
+ * color the array entry will contain that color value; otherwise it
+ * will contain NO_COLOR. Segments that are completely transparent
+ * will always have the value TRANSPARENT_COLOR.
+ *
+ * The PNG chunk type is "npTc".
