#124: Ensure I/O operations on images holding greater-than-8-bit values are
robust w.r.t. endianness
-----------------------+----------------------------------------------------
Reporter: levill_r | Owner: Olena Team
Type: task | Status: new
Priority: minor | Milestone: Olena 1.0
Component: Milena | Version: 1.0

-----------------------+----------------------------------------------------
Old description:
This might be difficult to check, since it's
platform-dependent. At
least, we should check this (with the build farm) on a host with an
endianness different than IA-32's or Intel 64's (e.g., a SPARC station).
According to http://en.wikipedia.org/wiki/Endianness,
* Intel IA-32 (and probably Intel 64 and AMD 64) are little-endian;
* Motorola 68k, Sun SPARC and IBM System/370 processors are little-
endian;
* PowerPC, ARM, DEC Alpha, MIPS, HP PA-RISC and Intel IA-64 processors
are bi-endian.
