Can I use Macports for Gimp maintenance?

Lukas, it would be great if you’re able to use MacPorts to package GIMP, and we’ll certainly do whatever we can to support your efforts!

I’ll start with a quick summary of where things stand, in case you haven’t done a lot of in-depth digging yet:

* glib2: We currently maintain three versions:
	* The default is 2.64.6, via port ‘glib2'
	* The next rev up is 2.66.8, via port 'glib2-devel'
	* And finally, the newest stable release is 2.72.3, via port 'glib2-upstream’
	* If you have a preference, you’ll want to install the desired one first. All dependents are setup to work with all three though, and will automatically use whichever one you have installed.

* Presently we only apply a small subset of patches for GIMP and gtk-2. (Though we’ve tried to cover the heavy-hitters, particularly related to screen-update performance on the latest macOS releases.) So if there are any that fix/improve runtime behavior, let me know!

Cheers,
