How would you draw something like that blue border above, where there's a solid line that fades out to total transparency on one side, in GIMP?
I just noticed the little GIMP tag, a quick search enabled me to find this tutorial for creating an 'Inner Glow' type effect in GIMP
The layer style Inner Glow
in Photoshop, and equivalents in other software, will do that for you:

Thank you. Even though I went a different direction, having gotten to know the keywords "inner glow" helped me research this further. – Smig Aug 9 '13 at 21:59
I found a simple way to achieve my goal by downloading the Gimp plugin Layer Effects, which adds an inner glow effect, among others, like what I imagine Photoshop already has built-in.
