Simplifications and potential bug

[AntonioNoack]

Hi, I was reading a lot of the library, because I ported it to use JOML instead of float[3]s.
I discovered multiple places like

if(a < b) return -1;
else if(a > b) return +1;
return 0;

This could be simplified with Integer.compare(a,b) or Float.compare(a,b) (depending on the type).

The bug I discovered is that in RecastContour.getCornerHeight() a boolean is passed, that probably originally was a reference. In Java, it just gets passed, and never set to true. (IntelliSense told me)

Well spotted. Thank you very much for reporting.
