Edward Welbourne 3a9e135d55 Exploit QVector3D::length() instead of duplicating its work
Calling the class-method dotProduct(x, x) in order to then take its
square root is a clumsy way to obfuscate x.length() - and lacks its
efforts (clumsy though they are) to limit rounding issues.

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.
