[Insight-developers] Multi-threaded source object (RandomImageSource)

[Will Schroeder]

Hi Folks-

I've rearranged some methods within ProcessObject, ImageSource, and 
FilterImageToImage to support
multithreading in the source objects; and also multithreaded RandomImageSource.

It uses vnl_sample_uniform() and as Lydia described, this function does not 
work right (we have notified the
vxl folks).
