 * Regex for validating a URI or URI Reference as defined in RFC3986.

 * A URI Reference is a URI without the scheme part. They are otherwise the

 * can't contain a ':'.
 *
 * This syntax does not have IPv6 address support and does not include the IPv4

The bit reduction formulas converts the colors to give a minimal error after converting back to 8 bit. The sum of the signed errors is 0 and the sum of absolute diffs are as small as possible.

The formulas that convert back to 8 bit are done using bit shifting which introduces a rounding error for some color values. However bit shifting creates nice symmetric patterns and seems to be how hardware does it.

8 bit -> 4 bit -> 8 bit
c4 = (c8 + 8) / 17
c8 = c4 << 4 | c4

8 bit -> 5 bit -> 8 bit
c5 = (31 * c8 + 127) / 255
