Detailed Description

This file was moved here from the src/ directory. It is meant to deal with endianness. It resided in a general blending lib. The other functions were only used during rendering. This single function remained. It should probably move to imbuf/intern/util.c, but we'll keep it here for the time being. (nzc)
