@JanoSlivka I think this fixes your issue but I don't want to merge it yet because it creates quite a bit of temporaries which hurt gc perf. Later if I find some time I'll optimize it and merge into master. Feel free to use as is.

Ok, thanks for fix this.

I tried it and I found a few problems:

• 1 problem:
  I zoomed at an angle to measure 8.49 to the red point.
  Step1:
  
  Step:2
  
  Step:3
  
  And the measurement changed from three points to two

• 2 problem:
  I zoomed to measure 2.72 to the red point.
  Step1:
  
  Step:2
  
  Step:3
  
  And the measured value is out

• 3 problem:
  Maybe it's a problem, maybe not, but if I measure the distance, the infinite line is still displayed
