Fixed fatal errors that broke the mod

[CAG2Mark]

There were two key errors in the original mod that made it not work.

1. When iterating through the list of controllers, if there was one exception in the entire process, the entire for loop would exit. This means that if in the list of controllers, a faulty controller is before the desired controller, the desired controller would never be reached.
2. The original code checked for float equality (namely, the mouse position to the double 0.0 exactly). Due to floating point errors, this is a very bad idea. The best solution is to compare a range of values (for example, -0.1 < x < 0.1).

I've fixed both these issues and can confirm the mod now works.

thanks will check this

@CAG2Mark after testing this pr it seems like its accepting devices with no movement causing it not work

I think this line is causing the problem @xCuri0 is referring to. ((-eps < px && px < eps) || (-eps < py && py < eps)) will return true if either px or py is almost zero. This will cause it to detect a not-moving mouse. Rather, the line should be:

if (px < -eps || px > eps || py < -eps || py > eps)

That will only trigger the condition if the mouse is actively moving rather than the other way around.
