PathView: fix warnings, oddities and whitespace

- avoid runtime conversion of float->double when initializing a qreal
- use qFuzzyCompare/qFuzzyIsNull to avoid direct comparison of
  qreal values
- don't test a float value as a bool by implicit casting(!)
  to check whether it's zero
- avoid implicit casts and old-style casts
- fix whitespace around comments
