Edward Welbourne 8095c33bcd Use qRadiansToDegrees() and qDegreesToRadians() more widely
Especially in examples, where we should show off our convenience
functions, prefer calling these functions over doing arithmetic with
M_PI (or approximations thereto) and 180 (give or take simple
factors).  This incidentally documents what's going on, just by the
name of the function used (and reveals at least one place where
variables were misnamed; the return from atan is in radians, *not*
degrees).

README

Qt is provided with a comprehensive canvas through the GraphicsView
classes.

These examples demonstrate the fundamental aspects of canvas programming
with Qt.


Documentation for these examples can be found via the Examples
link in the main Qt documentation.
