Joseph,

Actually you rolled back a correction make by Ton for the bug 4734:
http://projects.blender.org/tracker/index.php?func=detail&aid=4734

The bug was that premultiplied-images were drawn badly ;-)

Here is the commit mail for the previous correction:

Maybe a better solution to this issue would be to have a setting on 
image/viewer to specify if it's pre-multiplied or not, and use the 
correct blending mode according to this setting.

Regrads,
Stéphane
