Detailed Description

structure to hold specifications for an iir_filter object. This set of parameters has to be passed through from the calling code through the multithreading code to the worker threads where the filter objects are finally constructed. Rather than passing the parameters via some variadic mechanism, it's more concise and expressive to contain them in a structure and pass that around. The filter itself inherits its specification type, and if the code knows the handler's type, it can derive the spec type. This way the argument passing can be formalized, allowing for uniform handling of several different filter types with the same code. Here we have the concrete parameter set needed for b-spline prefiltering. We'll pass one set of 'specs' per axis; it contains:

the boundary condition for this axis
the number of filter poles (see poles.h)
a pointer to npoles poles
the acceptable tolerance
