[Feature request] Extend +/- to increase/decrease FOV

[barneycarroll]

The feature of extending +/- one step beyond 'no HUD' to remove the weapon view model is fantastic. The same principle could be extended for the purposes of photography mode to make further + inputs increment the FOV at intervals of 10 degrees; - would iterate back down until the the configured FOV (and then reinstate weapon view model, then extend HUD, shrink view, as per normal).

I did a quick hack for myself in gl_screen.c (line: 1045), by changing the condition value from 130 to 120

if (!crosshair.value || scr_viewsize.value >= 120)
        return;
