Feedback:User/Mtew/Fix dark vision adaptation

The 'dark adaptation' in GW1 is exactly the opposite of what happens in real life. Specifically, when entering a dark area, the 'gamma' of the display is decreased; going into a dark place shows less details than you can see from outside that place. In real life, the effect is exactly the opposite, effectively the 'gamma' of the 'display' increases; you can see things more clearly once you get your 'night vision'.

If this is implemented properly, it should be difficult to see into dark places from the outside. Once you enter the dark place, you should fairly quickly (pupilary response) be able to see some more details followed by a period where you can see more and more details (night vision response) as long as you don't look into bright areas. Looking out of a dark area into a bright area will initially be very 'washed out' with some improvement as you lose your 'night vision'.

While having both levels of response modeled would be nice, 'pupilary response' is easier to do since it only requires reading the ambient light level where the characters head is. The dark adaptation model requires a summary of the recent peak light levels over the entire display.
