Use qRadiansToDegrees() and qDegreesToRadians() more widely
These document what the arithmetic is actually doing; and save us an ad-hoc use of an approximate value for pi while we're about it. Task-number: QTBUG-58083 Change-Id: I82c5502af724b33ec598c5a9da76537f93a95eac Reviewed-by: Tomi Korpipää <tomi.korpipaa@qt.io>
