On inclusion, these macros should be defined:

AA_NAME_SUFFIX(str) appends to 'str' a string denoting this particular invocation of the file.

AA_BPP_SUFFIX(str) appends to 'str' the bit depth handled.

AA_ITER_COMPS(body) invokes the macro 'body' for each component, passing the component index as an argument.

On inclusion, these macros may be defined to a constant to improve performance, otherwise the quantity is fetched at run time.

AA_NCOMPS should expand to the number of interleaved components; if this not supplied, an argument is added for it.

This file is included multiple times, so should NOT have a guard around it.
