Maybe this is one of those ones like the latex
tag. It's misused so much that pgf
isn't a suitable tag. Whilst I can imagine a question being pure pgf
(for example, something using the maths parser or a package like pgfpages
), these are probably drowned in the morass of tikz
questions.
The solution for latex
is probably applicable. There should be a pgf-core
tag for questions that are really about pgf and not about tikz, whilst pgf
itself should be merged with tikz
.
To address Will's point: I would look at a tikz
question expecting to be able to make a contribution (meaning that I would reckon on being able to say something sensible more than 50% of the time), but with a pgf-core
tag then I would look expecting to learn something from those more advanced in the Dark Arts than me.
Combining this with Stefan's idea, this looks like a good idea:
- Rename
tikz
to tikz-pgf
- Merge
pgf
into tikz-pgf
- Make
tikz
and pgf
synonyms of tikz-pgf
- Create
pgf-core
