Hah! Judging from this and your other posts, you don't have the 
slightest clue about any kind of coding, let alone implementing 
something like this. If it's so easy, why are you asking for someone 
else to do it?

Warp is correct, it could be much more general and powerful than your 
suggestion. I've never liked having transparency values part of the 
color, it looks like copying the alpha channel in image formats. 
Separate control of transparency would greatly increase the flexibility 
of the program.
However, it isn't something that would be easy to patch into the current 
code, which has developed for over a decade on the assumption of 
5-component color vectors with two transparency components. I tried, as 
part of my old blurred transparency patch, and didn't make any useful 
progress. I may try again someday, when I have a lot of time to kill.
