any chance someone can try this in a host with different parameters?

[jaromil]

thanks Dan. Given the issues I think this won't make it in the release on time.

[ddennedy]

The issues are small that could be addressed very quickly for the release without imposing risk, but I do not know how to fix the most meaningful of them myself.

@d-j-a-y could you explain in further details how these parameters work? There are some preliminary translations done in downstream projects already, but we’re pretty confused what “Plans fade” and the rest of the parameters are.

@rschiang , it's true, i will do my best to fix me contribution. maybe removing sse2 specifcs and keeping 'layers fade', or removing this strange and glitchy parameter ... and found an explicit naming, description.

Fill free to build and play with it ... ! :-) Tips :

• First and second argument should >0,
• Third , ~ add or subtract image ....
• "Plans Fade"to 0 and others parameters set to 1 And you should see some explicit variations .... then well free to play deeper ;-)

Nota: 'Plans' is a french word,(lost in the code), relative to rgb layers

OK, I am basically OK with this now. We can merge this if you are ready.

[d-j-a-y]

Thanks to all of you!

[ddennedy]

@d-j-a-y ready to merge, or are there other changes you plan soon?
