Diagonal Snapping

[panther03]

Somehow snap the stick to a diagonal notch. This is trickier than cardinal snapping because there are several ways to do it.

You could

• calculate the angle using arctan, if it's within a configurable angle range from the notch point, then simply change the angle while keeping the magnitude
• essentially just give a point range around the notch where it will snap to that value, so if you're within 5,5 lets say of the range, itll just snap (will have to be adjusted for ax_t range, probably a % makes sense)

Depending on implementation, could be rolled in with #3.
