Created an attachment (id=6539)

Suggested patch.

Fix: When outputting a scanline, the default copy_alpha() was passing the 
byte width as appropriate for the source bitmap, not for the modified 
scanline. While they have the same width in pixels, their width in bytes 
may differ because of different colour depths. Bug 691494.

Note: My tests were not extensive.
