Hello, in terrain.pzdat... what does glow means?

This is an exchange between Maths and Yrfin from a couple years ago. I have not verified the info.

"Hello Yrfin,
I've just read your terrain.pzdat file and I have a few questions.
What is the exact meaning of the traits glow, lowsup, gndsup, airsup, navalsup, river and strait ?
What is a supply hex for units ? Indeed there is no concept of supply lines linked to supply sources.
Thank you in advance !
Greetings,
Maths "

"Hi, Maths,

from my knowlege:
"glow" - it means that terrain types with this trait will "glow" or "shine" if terrain glow is enabled in the in-game menu:
as it says it is used by the game for certain terrains like cities or forests so that units standing on these terrains stand out more from the background.

lowsup - 50% supply on such hex"
