Move to four points

When the Tracking state is entered, the scale constraint on Tracking Points has it's weight animated to 1. This breaks the tracking with the 4-point setup because the contacts get too far away from each other when the parent scales up. Originally, scaling up was done to making it very hard to lose tracking.

Should be fixed

I'm experiencing odd behavior when trying this version out in my avatar project using Gesture Manager. it only works as intended when frame stepping for some reason? otherwise, it seems to kinda move away from the contact sender in a semi-random fashion/direction until it no longer interacts with the contact sender. This does not occur with the version of the tracker currently in the main branch. Are you testing it in-editor? If so, how are you doing so?

aside: does the math used by this iteration make assumptions about the radius of the contact sender? (one of the writeups on discord appeared to discard the sender's radius as part of an approximation, assuming that it was 0, i think, but the information I can pull doesn't seem particularly clear on the matter, aside from using different math than my own attempt at this. (i didn't do anything with barycentric coordinates)
