Details
The Mac represents 16-bit RGB pixels (called direct format) as 5-5-5. It looks to me that the 16-bit blender (nsBlender::Do16Blend()) assumes 5-6-5 format. Here's the section of Inside Macintosh that talks about this: http://developer.apple.com/techpubs/mac/QuickDraw/QuickDraw-198.html#HEADING198- 58 Here's the figure that shows the 16-bit pixel format: http://developer.apple.com/techpubs/mac/QuickDraw/QuickDraw-198.html#MARKER-9-70
