/**
* \brief Generate a point set with blue noise properties
*
* Based on the paper "Parallel Poisson Disk Sampling with
* Spectrum Analysis on Surfaces" by John Bowers, Rui Wang,
* Li-Yi Wei and David Maletz.
*
* \param scene
* A pointer to the underlying scene
* \param shapes
* A list of input shapes on which samples should be placed
* \param radius
* The Poisson radius of the point set to be generated
* \param target
* A position sample vector (which will be populated with the result)
* \param sa
* Will be used to return the combined surface area of the shapes
* \param aabb
* Will be used to store an an axis-aligned box containing all samples
* \param data
* Custom pointer that will be sent along with progress messages
* (usually contains a pointer to the \ref RenderJob instance)
