I thought that the latest version of GIMP (2.8.2 is what I have now, following these instructions from WEBUPD8) and there's still no "Precision" choice under Image.
So this website indicates that 16-bit is ready if you're willing to do some compiling. I followed the link to the instructions. I've been hanging around Linux for a while now, but not ready to try all that on our daily-use PC.
Besides, those instructions are months old, and for 2.8-RC1. I woulda thought 2.8.2 would be further along. Maybe they pulled 16-bit back out?
Does anybody have the latest news on this?
Maybe it's time to just give up and buy Photoshop for the Windows side of our dual-boot?
