Detailed Description

template<typename T>
class scm_queue< T >

An scm_queue implements a templated producer-consumer priority queue.

Priority is given by the partial ordering on the templated type.

A "needs" queue is used by the render thread to delegate work to a set of loader threads. A "loads" queue is used by the loader threads to return their results to the render thread. In all cases, the loader threads perform blocking operations while the render thread uses non-blocking operations to ensure that frames are not dropped due to data latency.
