Description

Hex.formatUnsignedLongHex formats a long as hex digits into a byte array. It is used in the xloader (formerly "TDB1, tdbloader2").

Changing the implementation to process the hex digits in forward (high-to-low) order,there is better performance, possibly due to "mechanical sympathy" with the compiler or CPU caches.
