23 * Does it make sense to write 1..capacity ranges?
24 * Returns 0 if not, otherwise the number of ranges.
25 * @param values Sorted array of signed-integer values.
26 * @param length Number of values.
27 * @param density Minimum average range density, in 256th. (0x100=100%=perfectly dense.)
28 * Should be 0x80..0x100, must be 1..0x100.
29 * @param ranges Output ranges array.
30 * @param capacity Maximum number of ranges.
31 * @return Minimum number of ranges (at most capacity) that have the desired density,
32 * or 0 if that density cannot be achieved.
