Matthew has decided to not work on Kate, KDevelop, etc? hum. that'd be

that's a 5 line patch to fix if it is an issue: a convenience method that 
takes care of creating the temporary colour for you. it'll be interesting to 
see if that's really an issue or if in use (a) people don't care about the 
extra lines or (b) they blend colours which are temporary objects anyways and 
therefore don't need to store/keep one of them. so this may be a moot point, 
or it could be a pain. we'll have to see; there's a solution in any case.

that's correct; though this does it without an extra 500LOC class behind the 
scenes. the demand for the features that KColor brings seems to be limited to 
the people who are already looking to (and working on) pigment.

yes, i think Matthew was quite accomodating in that process. though i'm sure 
his "i'm going to have KColor in KDE no matter what" statements probably 
didn't help his case a lot, to be honest. =)

yes, it was very inneficient. and not even the good kind of inneficient (yes 
there are good kinds of that). there's something about restarting threads, 
going back and forth over and over, ad hominym jabs, etc.. that don't make 
things easy.

i am glad that such occurances tend to stand out as odd rather than the way 
things usually happen.

i'm not glad that we don't have a better way to handle these situations. this 
is where an active "technical working group" that has the backing of the 
community would have been astoundingly useful.

chalk one up in the "lessons to learn from" column =)
