Still -0 for me, because it will just complicate things later. Drawing
arrows should be done by renderer and should have configurable symbol,
size, color, spacing etc.

Anyway, if you're willing to apply that patch and make it
configurable, take in account these issues:
- missing test whether line.length() is not 0, otherwise you're later
dividing by 0
- update for PyQGIS is missing
- why #define PI when there's M_PI (in <cmath>)
- magic numbers in code (like arrowSize=10) are bad
