Revival of the GIMP developer website
GIMP has had a developer website for at least 2 decades (the Internet Archive traces back an early page in 2001), yet mostly unmaintained ever since 2009, which is a shame.
Since then, documentation for developers was scattered on the general website, the source repository itself and 2 wikis (developer and GUI wiki). As you may know, the developer wiki encountered problems recently. As for the GUI wiki, it is still there, though we plan to merge both wikis into our new developer website.
Rather than having duplicate documents all over the place, we want to consolidate developer documentation into a single point of entry.
