door closing & graphics updates - demo update (v14)

Door quick-close (door control version 4)

• Activated by pressing the local interaction button ([Space] / 🎮 [A] by default) together with moving in the direction that the character should stay after the door is closed.
• Only available while the door is fully opened (at least nearly 90 degrees), this state is most easily reached by quick-opening the door.
• As before, can be disabled by setting "Options/Control/Door control version" to version 3 or earlier.

Various

• Added the UI background blur effect (existing users need to opt in by enabling "Options/Graphics/Blurred scene UI backgrounds")
• Added adaptive exposure - increasing brightness if the image is too dark (can be disabled in "Options/Display/Adaptive exposure")
• Added increased camera vignette when zooming in (similar to how real cameras work)
• Fixed incomplete saving of player character’s door use state
