QtMath now provides M_PI constant, operations with degrees, and c++ provides round()
Summary:
Since QtMath library has a proper M_PI the define is not necessary anymore. Furthermore, C++'s round() function behaves in similar fashion to the ROUND2INT macro (rounding away
from zero). If this style of rounding is not specifically required, I suggest another revision to change it to rint(), which rounds towards even numbers.
