Add smoothing and other enhancements for Circular Mouse

[gddgddg]

I'm trying to make a profile combining gyro and horizontal mouselook with the right stick using a Dualshock 4. The circular mouse option is a nice idea for this (similar to Flick Stick from http://gyrowiki.jibbsmart.com/), but it's very jittery and doesn't work too well because it causes horizontal aiming to jump around too much. A little smoothing would make this much nicer.

In addition, it would be nice if sharp movements toward the center could cause horizontal movement to be more or less ignored or de-emphasized when using horizontal mouse. When I try to move the stick back to the center after a quick horizontal flick, my aim shifts a little bit, making it less accurate. De-emphasizing horizontal movement during centere-bound movement would help me a lot. I understand this might be very difficult to implement, so it's reasonable if this feature isn't worked on for a long time if ever. I just wanted to put it out there that it would be helpful for those of us using PS4 and PS5 controllers.

One solution to shaking horizontal aim is to make the deadzone very large, making only the edge of the right stick's range to affect horizontal aim. The problem with this is that it causes a lot of strain on my wrist and makes it difficult to play for more than 30 minutes or so. Having a small deadzone allows me to flick my view left and right very quickly and easily, leaving vertical movement and more precise aim to the gyro.

Anyway, even just smoothing would be great to have for the Circular Mouse option. That would be a big help considering how jittery it is alone.

Thank you for your consideration
