Get player Camera zoom

[vitovc]

This script finds camera zoom, helpful to detect camera hacks (fast zoom for sniper, super zoom (bigger zoom than vanilla) for sniper, zoom usage for rpg and so on). Please note this script is using hardcoded magical number (0.0357106) for normal screen (vanila vcmp, default field of view), if you are using widescreen mod (asi, modded .exe, etc) you will get incorrect values (this is also a way to detect widescreen mods).
