Yep the premultiplied feature was the first thing I tried when I noticed that
things weren't working the way I expected. According to the discussion in 2016,
Mister Lipka explained the source of the problem and corrected it in version
3.71. I don't consider myself to be a suitable beta tester (it took me over nine
years to discover this issue) so I'm using version 3.7.

What I should have done from the beginning is write the program in C which is
more suitable for this project. But it's pretty much done now and this is a
minor problem that I've been able to work around. The explanation from Mister
Lipka is very interesting though.
