Optics - Fixed magnification text flickering at 1.0x zoom level

[johnb432]

When merged this pull request will:

• Stops the magnification text in the top right corner from flickering when the magnification level is 1.0x.

---

0.25 call CBA_fnc_getFov select 1

does not return a stable value (it oscillates lightly around 1).

An example scope is the hlc_optic_atacr from NIArms.

Now it flickers even harder at 0.995 +-x

Instead, it should remember the last value and only update if delta > threshold.

[PabstMirror]

are there any scopes with magnification less than 1?

Good idea - any suggestions for a delta?

If you had success with x=0.995, maybe dx=0.005. Doesn't have to be a constant either, can depend on magnification if that helps. Needs trial and error.

It doesn't cache magnification levels below 1, so I'm not sure if there are any/if it's even supported at all.

In 669eddd I moved that code. I'm not sure if it's a good or bad idea to cache magnification levels >= 1 only. I tried without the >= 1 limitation briefly with BWMod and NIArms scopes and it seemed to work, but the tests weren't thorough. With the limitation I tested a bit more thoroughly albeit not enough, I couldn't find any problems.
